CERN purchases multi-user licenses for COMSOL Multiphysics

CERN, the European Organization for Nuclear Research and the world’s leading laboratory for particle physics, has purchased a multi-user license for COMSOL Multiphysics and a number of its add-on modules. Through this licensing agreement, this software is now available CERN wide for engineers and researchers. COMSOL Multiphysics enables them to conduct real-world simulations of any physics-based system during research, system design and development.

CERN is run by 20 European Member States, but many non-European countries are also involved, and scientists come from around the world to use CERN’s facilities. The Laboratory’s scientific and technical staff design and build particle accelerators and ensure their smooth operation; they also help prepare, run, analyze and interpret the data from complex scientific experiments. CERN has a permanent staff of 2500 researchers along with some 9500 visiting scientists who represent 608 universities and 113 nationalities.

“CERN attracts the world’s top scientists and researchers, and we are extremely gratified that these experts recognize COMSOL as one of the leading modeling codes and have asked to have CERN add this software to its arsenal of tools,” says Dr. Sven Friedel, Managing Director of COMSOL’s Zurich office, which handled the transaction. “This purchase clearly confirms the value of our software in assisting in the development and running of the world’s largest scientific experiments.”

COMSOL has enjoyed a growing interest at CERN. Pierre Baehler, Manager of the CAD/CAE Support Team for the organization, notes that “the use of COMSOL products started in 2007 when one user purchased an individual license. He was very successful with it, his colleagues got interested in it and not long thereafter a few more licenses were acquired. Meanwhile, though, we see graduate students and researchers who have worked with COMSOL products at their universities coming to CERN for their research. Following an increasing number of requests from them and CERN researchers, our engineering software selection committee decided to purchase concurrent network licenses which allow a wider access to the tool. COMSOL clearly has the potential to become an important tool for engineering applications at CERN.”

“One aspect that makes COMSOL so attractive to these users is its flexibility,” so explains Bernardo Bordini, a researcher who previously used the software while at Fermilab (Chicago, IL) was also the first COMSOL license at CERN. “Here at CERN we’re dealing with very non-conventional problems. For instance, in my studies of the magneto-thermo stability of superconductors, we are pushing the Maxwell Equations into a very nonlinear region. We thus need to modify the standard equations, and COMSOL allows me to do exactly that. In addition, we strongly rely on the software’s multiphysics capabilities. For example in some of our systems where we are sending current from room ambient temperature into a cryogenic environment, we have to closely examine the interplay of heat transfer, structural dynamics and electromagnetic effects. It’s not easy to find other software that can do it this well”.

The multiphysics capabilities of COMSOL are also attractive to Rob Veenhof, who is a Convenor of the simulation group of RD51, an international consortium of 73 universities and research laboratories from 25 countries working on the study of gas-based detectors. Besides research, the group also conducts courses around the world that introduce simulation tools to PhD students and postdocs within the collaboration, and such a course was recently conducted at CERN. Says Veenhof, “COMSOL is one of the finite-element packages we use to produce field maps that we then input into our own Garfield simulator. Further, COMSOL makes it far easier to study the onset of ‘streamers’. Here we work with some differential equations, which we can input directly into the software.” Veenhof adds that they are also studying very damaging gas discharges in the detectors and look forward to using the Plasma Module, which he now has access due to the new licensing agreement.

Yet another CERN experiment where COMSOL was of benefit is CMS, one of the particles detector in the Large Hadron Collider, an underground particle collider with a circumference of 27 km. Here, Bertrand Baudouy of CEA (the French Atomic Energy Commission) used the software to help design the cryogenic cooling system that keeps the magnet of CMS at -269°C (4 K). Baudouy notes that “I can now design the cooling tubes for a superconducting magnet in a week or so, work that previously took two to three months.”

No limit on the number of cores

Returning to CERN’s decision to purchase the software, Pierre Baehler adds, “Another factor that was attractive was the fact that a single network license allows CERN to run a COMSOL job on any number of cores or a compute cluster. This contrasts to many other products with a per-core licensing scheme. Not having a limit to the number of cores is extremely convenient for us because we are constantly upgrading and expanding our compute resources. There’s no need to acquire more licenses, we can instead run the software on new hardware and make use of the full compute capacity as soon as the hardware is installed.”

COMSOL’s Friedel, who has been assisting CERN researchers in fully exploiting the software, summarizes the collaboration this way: “At CERN, the world’s leading researchers are pushing the state of the art in a number of disciplines and in modeling. It’s clear that COMSOL is a technology enabler that allows them to truly unleash their creativity. This fits in exactly with COMSOL’s culture of intensively working with its users to drive innovation on both sides. We look forward to seeing more CERN researchers joining our very active community.”

CERN, the European Organization for Nuclear Research, operates the world’s leading laboratory for particle physics. Its business is fundamental physics, finding out what the universe is made of and how it works. Founded in 1954, CERN has become a prime example of international collaboration, with currently 20 Member States. Additional nations from around the globe also contribute to and participate in the research programs.

COMSOL Version 4.2a Unveiled at the COMSOL Conference in Boston

New version expanded with particle tracing, image-to-material conversion, and Digital Elevation Map import.

Today in Boston at its seventh annual User's Conference, COMSOL Inc. unveiled COMSOL Multiphysics version 4.2a, a major update of its market-leading multiphysics modeling and simulation environment. With the introduction of version 4.2a, which includes features that extend the reach of multiphysics analyses to new communities of engineers and scientists, COMSOL has created a tightly-integrated analysis platform that offers a breadth and depth unmatched in the industry. Version 4.2a sees the debut of two new products, Particle Tracing Module and LiveLink™ for Creo™ Parametric, as well as many new features that bring greater modeling power to the users of COMSOL Multiphysics and its application specific add-on modules.

“As more and more design teams turn to simulation for product innovation, COMSOL is committed to providing easy-to-use tools that support creativity and save precious development time,” comments Svante Littmarck, CEO of COMSOL. “With Version 4.2a we have made a significant upgrade of COMSOL Multiphysics’ core capabilities that will ensure all customers get the most out of their modeling tools throughout the product development process. We’re also very excited about making particle tracing available for both single physics and multiphysics simulations.”

Image-to-material conversion bypasses geometry creation and speeds up simulation

Image-to-material conversion can shorten time to solution for image-based simulation dramatically. With this new capability engineers and scientists in industries such as life science and semiconductors can now bypass both geometry creation and computational-demanding meshing of microscopic details. They can use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM), computed tomography (CT), or magnetic resonance imaging (MRI).

An important application of image import is the easy computation of equivalent volume-averaged material properties for highly inhomogeneous or porous materials. This includes properties such as conductivity, permittivity, elasticity, or porosity, and it allows for converting spatially distributed values to a single representative averaged value. Such equivalent material properties can then be used for simulations of larger structures, avoiding detailed microscopic information. This modeling approach has several advantages such as avoiding the often difficult operations of image segmenting and image-to-geometry conversion. It also brings greatly simplified meshing, less memory usage, and shorter computation times—all of which are crucial when the same analysis needs to be repeated many times for different images.

An imported image is made available as a general COMSOL interpolation function that can be used for any modeling purpose. Certain 3D analyses are made possible by importing multiple images representing sections of a 3D structure.

Digital Elevation Map import enables quick geometry creation for geophysics simulation

Version 4.2a also comes with a new Digital Elevation Map interpolation feature that directly supports the importation of topographical surface data formatted in the U.S. Geological Survey's (USGS) Digital Elevation Map (DEM) file format. Users can freely combine DEM surfaces with other surfaces and solids to form a volumetric representation of both geometry and mesh. Multiple DEM surfaces can be combined and intersected as well as embedded inside of other geometrical objects to form composite structures. Geometric structures resulting from DEM import are generic in the COMSOL environment and handled in the same way as are mechanical CAD structures. This means that the full power of COMSOL Multiphysics is available for DEM geometry representations and can be applied to any single physics or multiphysics simulation such as subsurface flow, electromagnetics, acoustics, and geomechanics.

CAD modeling and new LiveLink™ for Creo™ Parametric

COMSOL is a firm believer in the collaboration within design teams and across departments. The new expansion of the COMSOL LiveLink™ CAD interoperability products to embrace Creo Parametric design software from PTC® is another major step in support of these efforts. With the new LiveLink for Creo Parametric, COMSOL Multiphysics seamlessly integrates with the latest design software from PTC. By establishing an associative connection between the two applications any changes to a feature in the Creo Parametric CAD model automatically update the geometry in COMSOL Multiphysics while retaining physics settings. Additionally, all parameters specified in Creo Parametric can be interactively linked with your simulation geometry, which enables multiphysics simulations involving parametric sweeps and design optimization to sync up with the CAD program. The LiveLink for Creo Parametric includes all the capabilities of the COMSOL CAD Import Module and enables import and defeaturing of CAD files from all major CAD packages.

The Parasolid® geometry kernel from Siemens PLM Software is now the default geometry kernel for users of the CAD Import Module and the LiveLink products for CAD. Parasolid enables the handling of more advanced geometry objects for users of any of the LiveLink products, which include versions for AutoCAD®, Autodesk® Inventor®, Creo™ Parametric, Pro/ENGINEER®, SolidWorks®, and SpaceClaim®.

COMSOL Multiphysics’ extensive Model Library is now accessible from within the One Window Interface that is included with the LiveLink for SolidWorks. Animations and images can now be created from the One Window Interface. Additionally, a series of performance enhancements make for quicker synchronization of large models.

Particle Tracing Module now available

The Particle Tracing Module extends the functionality of the COMSOL Multiphysics environment for computing the trajectory of particles in a fluid or electromagnetic field, including particle-field interactions. Any COMSOL add-on module combines seamlessly with the Particle Tracing Module, giving users access to additional modeling tools and fields to drive the particle motion. Applications include flow visualization, mixing, spraying, particle separation, mass spectrometry, ion optics, beam physics, ion energy distribution functions, acoustic streaming, and ray tracing.

“The new Particle Tracing Module is a game changer,” comments Bjorn Sjodin, VP of Product Management. “Now particle trajectories can be computed and visualized for any particle-field analysis. This will appeal to new groups of engineering communities that can use particle tracing for both traditional CFD and electromagnetics analysis and for more novel combinations with any other physics simulation. Customers will also appreciate the speed of the particle tracing, which makes it convenient to handle hundreds of thousands of particles in one and the same simulation.”

A variety of different forces are allowed to act on the particles, including forces on charged particles in electric or magnetic fields, drag forces in CFD, electrophoretic forces in microfluidics, acoustic streaming forces in acoustics, and user-defined forces. Loss or gain of mass, charge, or similar quantities may be represented as auxiliary variables and equations for each particle along its trajectory. Particles can be massless or have mass, where the movement is governed by Newtonian, Lagrangian, or Hamiltonian formulations from classical mechanics. Low-level access to the mathematical formalism is available for highly customized simulations.

Results and visualization

Version 4.2a's new Join Data Set function compares solutions corresponding to different meshes, time steps, or parameter values. Users can form combinations of solutions using the operation's difference, sum, product, quotient, and more general and explicit expressions. An important application for the Join Data Set is to plot and evaluate the difference between two solutions in a mesh convergence study.

Any scalar quantity of interest can be visualized by slice plots or isosurface plots. Quantities visualized can be one of many predefined expressions or be typed in as a user-defined expression. A new addition to slice and isosurface plots is the slide controller for the location of the slices and surfaces within the plots.

Incident sun radiation in the Heat Transfer Module

External radiation sources can now be defined in the Heat Transfer Module as sources at infinity or as point sources at a finite distance. This option is available in the Heat Transfer physics interface and any physics interface that supports surface-to-surface radiation. When defining a source at infinity, users input the power per unit area. This is typically applied for incident sun radiation in various types of renewable energy applications.

Another new important feature of the Heat Transfer Module is that users can define radiation on both sides of a boundary when surface-to-surface radiation is used. This new option is available in the Heat Transfer physics interface and any physics interface that supports surface-to-surface radiation.

Electromechanics multiphysics interface in the MEMS Module

A new Electromechanics multiphysics interface combines solid mechanics and electrostatics with a moving mesh to model the deformation of electrostatically actuated structures. Applications include biased resonator computations with modal and frequency-response analysis as well as pull-in voltage computations. A suite of new electromechanical tutorials are available showing 2D and 3D models of a biased resonator for stationary analysis, the frequency response, the normal modes, the pull-in voltage, and the transient response.

New communities of engineers and scientists


Multiphysics simulation technology is enabling engineers and scientists to realize their boldest design concepts and help businesses stay ahead of their competition. COMSOL Multiphysics Version 4.2a will make it easy for new user communities to find productive tools for solving their current design challenges.

Version 4.2a highlights

Major Upgrade to COMSOL's Acoustics Module Enables Realistic Acoustic Simulations of Mobile Devices and Automotive Components

COMSOL, Inc., today announced the release of a major upgrade of its add-on Acoustics Module for its flagship product COMSOL Multiphysics. This latest version of the Acoustics Module offers new capabilities and expanded multiphysics user interfaces for simulating thermoacoustic effects, poroelastic waves, acoustic-shell interactions, and piezo-acoustic devices. The new version of the Acoustics Module is available immediately.

“This release of the Acoustics Module brings a new level of predictive power to acoustic simulations,” says Dr. Mads J. Herring Jensen, technical product manager for acoustics at COMSOL. “For the first time, manufacturers of acoustic devices for smart phones, hearing aids, and earpieces can perform thermoacoustic simulations with an industry-standard commercial multiphysics software package. The ability to combine such simulations with electrical circuits and structural vibrations raises the bar for state-of-the-art acoustics simulations of mobile devices.”

Additional application areas for the Acoustics Module, adds Herring Jensen, include speakers, microphones, and sonar devices as well as noise control in areas such as muffler design, sound barriers, and building acoustics. The module's physics interfaces provide easy-to-use tools to model acoustic pressure wave propagation in air, water, and other fluids. The Acoustics Module also enables users to model vibrations and elastic waves in solids and piezoelectric materials, as well as their bidirectional interaction with a surrounding fluid, easily.

“Our analysis of acoustic applications has ranged from the design of miniature microphones and loudspeakers, development of MEMS-based photoacoustic and piezo-acoustic technologies, optimization of room design for acoustic energy distribution, and identification of sources for noise emission. Each of these applications has required the implementation of additional functionality into COMSOL Multiphysics to provide accurate analysis of real world systems,” comments Dr. Jeffrey S. Crompton, Principal of AltaSim Technologies, Columbus, OH. Through his company, Dr. Crompton provides a range of products and services such as customized computational analyses and the development of functional prototypes for market sectors including medical devices, defense, petrochemical refining, automotive, and materials development.

The new capabilities of the Acoustics Module are fully compatible with all the COMSOL add-on modules. Any acoustics phenomena can link to any other physics effect – a feature that is crucial for real-world precision simulations of acoustics devices. “The upgrades in this version of the Acoustics Module will provide all users with access to critical functionality associated with analysis of acoustics phenomena. These additions greatly enhance the flexibility of COMSOL Multiphysics and will allow users to integrate relevant phenomena more easily and develop more accurate simulations of real-world performance. This will benefit all developers of new products and technologies and increase the rate at which new technologies can reach the marketplace,” concludes Dr. Crompton.
Mobile Devices and Thermoacoustics Simulations

The new modeling tools for thermoviscous acoustics in the Acoustics Module enable highly accurate simulation of miniaturized speakers and microphones for hand-held devices. The ability to include thermoviscous acoustics, also known as thermoacoustics, in a simulation is necessary to accurately model acoustics in geometries with small dimensions. Near walls, viscosity and thermal conduction become important considerations because they create a viscous and a thermal boundary layer where losses are significant. The new thermoacoustics capabilities of the Acoustics Module take such effects fully into account.

Automotive Components and Poroelastic Waves

When creating a virtual prototype of an automotive component with a fibrous or porous filling, how to represent the filling's acoustic damping properties has been a challenge. The Acoustics Module’s new poroelastic wave functionality offers a new and more accurate approach to this challenge.

With traditional simulation methods, engineers confronting this challenge would approximate their filling with a so-called equivalent fluid model. This approach often produced an approximation of reality that was too rough. Using the new poroelastic wave functionality in the Acoustics Module, engineers enter solid and fluid properties into their model directly and the damping is accounted for in the simulation automatically.

“Determining the damping properties of an equivalent fluid model requires a lot of engineering experience,” comments Dr. Herring Jensen. “Even if you've been successful in the past, it is often not valid for the full range of studied parameters. It will never be as accurate as the Acoustics Module's new poroelastic model, which can be used to model virtually any porous medium for a wide range of frequencies.”
Acoustics Module Version 4.2 Highlights

Enables rapid prototyping and optimization of acoustic devices and transducers
Accelerates the investigation of acoustic-induced vibration phenomena in devices
Ideal for the study of material-dependent acoustic phenomena
Works with real CAD geometry models and leading CAD software and formats

New Electrodeposition Module for COMSOL Multiphysics Released

Expansion module empowers shape and composition modeling and simulation of electrodeposits for metallic electroplating, electroforming, and decorative, wear and corrosion-protective coating.

COMSOL, Inc., today announced the release of the Electrodeposition Module, a new add-on expansion module for the company's flagship product COMSOL Multiphysics. The Electrodeposition Module provides engineers the ability to model and simulate the shape and composition of electrodeposits for such processes as copper and gold electroplating in the electronics industry, wear and corrosion-protective coatings of mechanical parts, decorative coatings such as chrome and nickel plating of automotive parts, as well as electroforming of thin and complex manufactured parts.

"The Electrodeposition Module allows for very accurate descriptions of the electrochemistry, heat transfer, and fluid flow in electrochemical cells used for electrodeposition,” says Dr Henrik Ekstrom, technical program manager for electrochemical applications at COMSOL. “With this tool, developers can run realistic simulations of electrodeposition processes, from the micro-scale on up, using interfaces tailored for exactly these applications. This saves a lot of time and money in the development process."

The Electrodeposition Module enables realistic simulations for investigating the influence of cell and electrode geometry, chemistry, material properties, and operating conditions. The shape and composition of a deposited metal layer is modeled with either a thickness variable for very thin layers or as a moving boundary for thicker layers.

"You don’t have to be a modeling expert to make good use of COMSOL," comments Dr. Philippe Gendre, head of research and development at the electroplating firm PEM in Siaugues, France. "By using COMSOL we have made significant advances, often including savings between 10% and 30% of the metal we deposit during electrolysis. With the new Electrodeposition Module, model set up of the electroplating process is very easy. The module includes all the electroplating physical effects in a single user interface, including conductive media for the electrical current, Navier-Stokes for the electrolyte flow, and electrokinetic flow to simulate the transport of species."
Tailored Interfaces and Model Library

The Electrodeposition Module has interfaces for secondary and tertiary current distribution. Laminar flow and heat transfer interfaces, including predefined couplings for electrochemical cells, are also included in the module. Turbulent flow and two-phase flow capabilities are available in combination with COMSOL’s CFD Module.

The secondary current distribution interfaces handle the electrode kinetics at the electrode surfaces and the current conduction in the electrodes and electrolyte. The tertiary current distribution interfaces also include the material balances of the ions in the electrolyte, with transport by diffusion, migration, and convection, which can be modeled together with fluid flow in the cell.

Both the secondary and tertiary current distribution interfaces include detailed modeling of multiple electrode reactions (using, for example, Butler-Volmer expressions), the shape and composition of the deposited layer, and also of possible dissolution processes at the anode.

Each of these functionalities are available as predefined options in the graphical user interface and in combination with any other COMSOL add-on product. The Electrodeposition Module comes with a model library that includes tutorials and benchmark models demonstrating its workflow and capabilities.

“Modeling and simulation are cost effective ways for understanding, optimizing, and controlling electrodeposition processes, so it’s great news for the simulation community that we now offer the Electrodeposition Module for COMSOL’s powerful multiphysics environment,” comments Dr. Ekstrom. “Electrodeposition processes previously beyond reach for simulations are now available in a standard simulation environment with an easy-to-use user interface.”
Electrodeposition Module Highlights

COMSOL Introduces the Microfluidics Module

The new Microfluidics Module from COMSOL provides an integrated environment for modeling microfluidic and rarefied flows.

COMSOL, Inc., the makers of the award winning COMSOL Multiphysics simulation software, today announced the release of the Microfluidics Module. Based on COMSOL Multiphysics, the Microfluidics Module brings easy-to-use tools for the study of microfluidic devices and rarefied gas flows. The module is designed for researchers, engineers, and experimentalists in the fields of microfluidics and vacuum science. Target application areas include lab-on-chip devices, digital microfluidics, biosensors, electrokinetic and magnetokinetic devices, inkjet technology, and vacuum system design. The module is accompanied by a suite of tutorial and industrially relevant models that serve as both instructional examples and as a foundation for future work.

“The simulation of microfluidic devices frequently requires multiple physical effects to be incorporated,” comments Dr. James Ransley, developer of the Microfluidics Module with COMSOL, Inc. “The Microfluidics Module offers a range of tools to deal with single- and multi-phase flows, transport and chemical reactions, flow in porous media, and rarefied flows. Thanks to the single user-interface in COMSOL for modeling all physics, these phenomena can be seamlessly coupled with thermal and electromagnetic effects.”
Specialized Microfluidics Interfaces

The Microfluidics Module includes interfaces for single-phase flow. With these interfaces users can simulate such applications as compressible gas flows at low pressures, non-Newtonian flows (for example blood flow), and laminar and creeping flows that typically occur in lab-on–a-chip systems.

A particular strength in this module is its modeling interfaces for executing two-phase flow simulations using the level set, phase field, and moving mesh methods. A variety of important fluid-interface effects are included such as surface tension forces, capillary forces, and Marangoni effects.

These flow simulation tools and the multiphysics capabilities of COMSOL make it easy to set up coupled electrokinetic and magnetohydrodynamic models for the simulation of electrophoresis, magnetophoresis, dielectrophoresis, electroosmosis, and electrowetting effects that are used alone or in combinations in both existing and emerging passive electronic display technologies for their basic function.

The COMSOL Model Wizard lets Microfluidics Module users choose from a wide range of functionalities to address fluid flow and other coupled phenomena.

“We strongly believe that the Microfluidics Module will offer a very attractive set of tools for our electronic display customers,” comments Dr. Ransley.

Expanding Multiphysics Applications with COMSOL Version 4.2

Burlington, MA — COMSOL, Inc., announced today the release of the latest version of COMSOL Multiphysics, its award-winning simulation environment. Version 4.2, which expands the scope of applications covered by COMSOL, is now available and will be shipped to all customers with current subscriptions.

“The vision behind Version 4 was to provide a foundation for our customers to reach broader audiences,” says Svante Littmarck, President and CEO of COMSOL. “The implication, and what we’re delivering with 4.2, is an expanded product offering based on that platform.”

Version 4.2 expands the applications covered by COMSOL with three new application modules – Microfluidics, Geomechanics, and Electrodeposition – and new LiveLink interfaces for AutoCAD® and SpaceClaim®.

“This release really bolsters our offerings to meet market demands in several directions,” says Littmarck. “Mechanical, electromagnetic, chemical, fluid, and CAD interoperability are all covered in this release. Even areas not explicitly addressed will benefit from the improved solver technology.”

“The list of features included in Version 4.2 is indeed impressive,” adds Littmarck. “By any measure, this is a major release. General geometry and meshing, solvers, postprocessing, and, as COMSOL’s customers have come to expect, user interface enhancements have all been upgraded. These new capabilities reach all products throughout the COMSOL environment, both existing and new.”

Core multiphysics capabilities accelerate simulation performance

Central to this release are the core development initiatives undertaken by COMSOL. The result is improved and expanded multiphysics simulation performance for all users. New capabilities target geometry, mesh, and solver functionality. The impact is primarily on what is already a strength of COMSOL: speed.

Version 4.2 includes new virtual geometry tools for creating a mesh that identifies the essential parts of the original CAD model to enable faster and more memory efficient solving. Time-dependent adaptive meshing and automatic remeshing tightly link solvers and meshing algorithms for any moving mesh analysis. Models with moving diffusion fronts are solved more efficiently as are simulations involving removal and deposition of materials.

The new Parametric Surfaces feature allows for creation of surfaces based on analytical expressions or look-up table data. This is especially crucial for importing topographical data for earth science applications.

The COMSOL direct solvers have been multicore and cluster-enabled for several years. With Version 4.2, the multiphysics assembly algorithms and iterative solvers have now also been parallelized, bringing you faster and more memory-efficient computations on virtually any type of computer platform, from laptop to cluster.

“The parallelized assembly means that a lot of users get a lot of speed,” comments Bjorn Sjodin, Vice President of Product Management with COMSOL. “Benchmark tests indicate a speed-up of 425% for a laminar flow static mixer and 164% increase for a microfluidic lab-on-a-chip simulation.”

Updated Model Builder brings new convenience tools to the modeling desktop

In Version 4.2, COMSOL has responded to customers requests with a new Report Generator for publishing results data. For a given model, this integrated, customizable tool lets users create data-rich HTML reports of varying degrees of detail, from brief to complete. Several reports can be added to a single model, enabling users to communicate all their important data in a well-organized, easy-to-read format.

The COMSOL Desktop with the Model Builder is COMSOL’s breakthrough user interface first introduced with Version 4.0. Drag-and-drop is now supported in the Model Builder tree to quickly edit the contents of a model. The presentation of simulation results is also updated. In the Model Builder, default plots are customized to adapt to the physics in the model with descriptive names. New plot types include histogram plots for statistical analysis, Nyquist plots for frequency response studies, and ribbon plots for flows.

CAD interoperability

CAD interoperability has always been important to COMSOL users, and this core aspect of simulation has been expanded significantly in Version 4.2.

The LiveLink for SolidWorks® interface has been extended with a One Window Interface where a SolidWorks user can stay inside of the SolidWorks environment and work synchronously with COMSOL Multiphysics.

The new LiveLink for SpaceClaim interface fuses direct modeling and multiphysics simulation in a tightly integrated environment. Similarly, with the new LiveLink for AutoCAD users can transfer a 3D geometry from AutoCAD to COMSOL Multiphysics. For both products, the synchronized geometry in the COMSOL model stays associative with the CAD geometry in its native format. This means that settings applied to the geometry, such as physics or mesh settings, are retained after subsequent synchronizations. The LiveLink interface is also bidirectional, allowing users to initiate a change of the CAD geometry from the COMSOL model.

Application-specific news

The Acoustics Module features new dedicated modeling tools for thermoviscous acoustics that enable highly accurate simulations of miniaturized speakers and microphones in cell phones and other handheld devices. This type of analysis will be increasingly more important as markets come to expect full, high-quality audio experiences in small packages.

The Structural Mechanics, MEMS, and Acoustics Modules offer new powerful and easy-to-use tools for prestressed analysis of eigenmodes and frequency response. Structures modeled with the Solid Mechanics interface can be prestressed by mechanical, thermal, or arbitrary multiphysics-based loads.

The new High-Mach Number Fluid Flow interface in the CFD Module applies to viscous, compressible flows with velocities greater than 0.3 times the speed of sound. The flow can be choked or non-choked and shock waves may or may not be present. The interface is suitable for designing nozzles, pipe networks, and valves, and for modeling aerodynamic phenomena.

For heat transfer in thin layers, a new multilayer option in the Heat Transfer Module makes it easy to model thin structures with multiple layers of different conductivity quickly.

The Chemical Reaction Engineering Module and the Plasma Module have been enhanced with new surface reaction tools for bidirectional adsorption-type simulations where surface species communicate with species of the surrounding bulk. Important applications include chemical vapor deposition (CVD) as well as plasma-enhanced CVD. The Batteries & Fuel Cells Module now features a new AC Impedance Study type for simulating electrochemical impedance spectroscopy (EIS). A new Surface Reactions interface enables modeling of surface reactions on boundary surfaces. The updated Batteries and Fuel Cells Material Library now comes with common battery electrode materials and electrolytes.

The RF Module features new tools for efficient plasmonics simulations where coefficients for refraction, specular reflection, and first-order diffraction are all computed as functions of the angle of incidence. This analysis is made possible by a new Floquet-type periodic boundary condition.

The Microfluidics Module

The new Microfluidics Module brings easy-to-use tools for the study of microfluidic devices and rarefied gas flows. Important applications include simulations of lab-on-a-chip devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems.

In addition to enhanced interfaces for single-phase flow, Microfluidics Module users have dedicated interfaces for two-phase flow using the level set, phase field, and moving mesh methods. Each of these interfaces includes surface tension forces, capillary forces, and Marangoni effects.

COMSOL’s general-purpose multiphysics features make it easy to set up coupled electrokinetic and magnetodynamic simulations such as electrophoresis, magnetophoresis, dielectrophoresis, electroosmosis, and electrowetting. The chemical diffusion and reactions for dilute species interfaces included in the Microfluidics Module enable the simulation of processes occurring in lab-on-a-chip devices. For simulating rarefied gas flows, specialized boundary conditions that activate flow simulation in the slip flow regime are provided.

A new free molecular flow interface using the fast angular coefficient method allows for simulations where the molecular mean free path is much longer than the geometric dimensions. Combined with COMSOL’s LiveLink interfaces for industry-standard CAD packages, this tool is invaluable for vacuum system design, allowing quick parametric studies of chamber geometries and pump configurations.

The Geomechanics Module

The new Geomechanics Module is a specialized add-on to the Structural Mechanics Module that enables simulations of geotechnical applications such as tunnels, excavations, slope stability, and retaining structures. The module features tailored interfaces to study plasticity, deformation, and failure of soils and rocks, as well as their interaction with concrete and human-made structures.

A variety of material models for soils are provided: Cam-clay, Drucker-Prager, Mohr-Coulomb, Matsuoka-Naka, and Lade-Duncan. In addition to the built-in plasticity models, user-defined yield functions can be created using the equation-based user interface provided by the COMSOL Multiphysics environment. Dependencies of a computed temperature field as well as other field quantities can be blended into these material definitions.

The Geomechanics Module is also a powerful tool for modeling concrete and rock materials. The Willam-Warnke, Bresler-Pister, Ottosen, and Hoek-Brown models, which are available as built-in options, can be adapted and extended by users to a more general class of brittle materials. Additionally, the Geomechanics Module can easily be combined with analyses from other COMSOL modules such as the porous media flow, poroelasticity, and solute transport functionality of the Subsurface Flow Module.

The Electrodeposition Module

Modeling and simulations are cost effective ways for understanding, optimizing, and controlling electrodeposition processes. A typical simulation yields the current distribution at the surface of the electrodes and the thickness and composition of the deposited layer. They are used to study important parameters such as cell geometry, electrolyte composition, electrode kinetics, operating voltages and currents, as well as temperature effects.

The Electrodeposition Module brings the power of COMSOL Multiphysics to simulate electrodeposition processes. Easy-to-use physics interfaces are provided for primary, secondary, and tertiary current distribution models, while very accurate geometric representations of deposited layer buildup are included as model parameters.

The Electrodeposition Module is applicable to a variety of diverse applications including; metal deposition for electronics and electrical parts, corrosion and wear protection, decorative electroplating, electroforming of parts with thin and complex structures, and metal electrowinning.

The expanding multiphysics universe

COMSOL Multiphysics 4.2 represents a significant expansion of the software’s applications, features, and functionality. Version 4.2 empowers current users to do more with their simulation environments, while new industries will now be able to leverage the innovation of multiphysics simulation. With this release, COMSOL continues to deliver on its promise to supply the science and engineering markets with the state-of-the-art simulation products for an expanding set of applications.

In the spirit of existing COMSOL products, each of the interfaces can be customized, modified and extended in arbitrary ways by the user.

Modeling the interaction between the plasma and an external electrical circuit is an important part of understanding the electrical characteristics of a discharge. The Plasma Module provides tools to add circuit elements directly to a 1D, 2D or 3D model. Alternatively you can import an existing SPICE netlist into the model. The plasma chemistry is specified either by loading in sets of collision cross sections from a file, or by adding reactions and species directly in the user interface.

The module includes a set of fully documented models of:
• Capacitively coupled plasma (CCP)
• Microwave plasma
• DC discharge
• Dielectric barrier discharges(DBD)
• Reactive gas generator
• Thermal plasma
• The Gaseous Electronics Conference (GEC) reference cell

Users can simulate reaction systems ranging from micro-reactors in biotechnology to unit operations in chemical processes and gain essential knowledge early in the development phase. The net result is more cost-effective and efficient development cycles for both products and processes.

“The Chemical Reaction Engineering Module is suitable for a diverse range of product and process development applications,” says Henrik von Schenk, Chemical Engineering Product Manager with COMSOL. “It’s particularly useful in the design of sensors for analytical instruments as well as for designing catalysts and filters in automotive exhaust systems. The Chemical Reaction Engineering Module will be especially valuable when developing products and processes in industries like consumer products, fine and specialty chemicals, pharmaceuticals, and bulk chemicals.”

The Chemical Reaction Engineering Module, which combines functionality of two earlier modules, the Chemical Engineering Module and the Reaction Engineering Module, leverages the newly re-engineered COMSOL version 4 architecture to deliver major new functionality and superior usability. With the new module, engineers and scientists can investigate chemical reactions under the controlled conditions of perfectly mixed systems in laboratory studies. Since reactions are directly accessible in a single easy-to-use interface, users can study the influence of multiple concentration and temperature variations in real operating conditions.
“The fusion of our premier chemical engineering capabilities into a single dedicated solution offering an all-inclusive, easy-to-use environment is a great convenience for our customers,” says von Schenk. “Productivity jumps with the new workflow and the ease with which users can manage species, reactions, and material and energy transport in one simulation.”

The Chemical Reaction Engineering Module’s easy-to-use customizable interfaces for defining chemical reactions, mass and energy transport, and porous media flow help users simulate reacting systems accurately. Fully integrated in the COMSOL Multiphysics model set up, the chemical reaction interface enables users to simply type in their chemical reaction formulas. The software then automatically computes the reaction kinetics as well as defines the mass and energy balances. When done, the resulting mass and energy balances are ready to be used to solve the reactor models for perfectly mixed systems of batch reactors, semi-batch reactors, CSTR, and plug-flow reactors.


Users can easily move up from these smaller, less computationally demanding simulations of perfectly mixed reactor models to larger-scale simulations of time- and space-dependent models. “The Chemical Reaction Engineering Module helps you make smart design decisions quickly using comparisons between ideal reactor models and detailed time and space simulations,” explains von Schenk. “It lets you handle simulations beginning at a simple level, which makes it easy to evaluate the chemistry of a system and find reaction time scales, temperatures, and ideal operating conditions. Then, you can use the identical model to run full 3D simulations for investigating and designing processes and reactors in real-world operating conditions.”

The Chemical Reaction Engineering Module provides interfaces for mass transport that describe species transport by diffusion, convection, and migration in dilute and concentrated solutions. These interfaces can also describe transport in free and porous media. Based on principal physics effects that come as standard interfaces in COMSOL, laminar flow and heat transfer can be included in the simulation as well. Still, no matter what physics effect is involved, model set up is quick and follows the same intuitive operations. Users can also add and remove chemical reactions and species as well as change reaction mechanisms on the fly. Users can maintain several studies each with different chemistries and different operating conditions in the same model.
Import Thermodynamic Property Data Into COMSOL

The Chemical Reaction Engineering Module is compliant with CAPE-OPEN standards for modeling, simulating, and designing the operations of chemical processes. Additionally, it has the ability to read CHEMKIN® files, which define complete reacting systems, including physical and thermodynamic properties, for combustion, atmospheric chemistry, and other gas-phase reacting systems.

With the Chemical Reaction Engineering Module’s built-in CAPE-OPEN Wizard, users can combine components from multiple third-party software vendors in their COMSOL simulations. An integrated CAPE-OPEN browser makes finding and selecting thermodynamic and physical property information in external property data packages easy. This flexible combination of openness and ease of use can lead to high-fidelity descriptions of such properties as viscosity, density, heat capacity, and other thermodynamic properties for gases and liquids.

COMSOL Multiphysics Version 4.0 Now Shipping

BURLINGTON, MA — COMSOL Inc. announces that version 4.0 of its multiphysics simulation software is now shipping. First unveiled at the 2009 users conference in Boston, COMSOL Multiphysics version 4.0 features an all-new user interface that makes the power of multiphysics simulation available to a wider audience of scientists and engineers. Both expert analysts and non-experts alike will benefit from the organized layout and streamlined model-building process. Along with the release of version 4.0, COMSOL also announces the release of a series of new LiveLink™ options that tightly integrate COMSOL Multiphysics into the mainstream product design workflow. New LiveLink products are now shipping for Autodesk® Inventor®, Pro/ENGINEER®, SolidWorks®, and MATLAB®.

“It feels great to make version 4.0 available,” comments Svante Littmarck, President and CEO of COMSOL, Inc. “We believe this release represents a bold step forward in usability that will increase productivity and problem solving capacity.” Version 4.0 is also a platform for accelerating the pace of development of new functionality. “Customers will notice this effect in the very near future: version 4.0a, available this June, includes three new modules for CFD, Plasma, and Batteries & Fuel Cells,” says Littmarck.
COMSOL Desktop - New Breakthrough User Interface

Model set up is smooth and direct, making tough problems quick and easy to solve. Version 4.0 brings an unprecedented level of clarity to product design simulation by combining an organized model overview and a streamlined model-building process in the new COMSOL Desktop. It uses functional form, structure, and aesthetics as the means to achieve simplicity for modeling complex physical realities. For instance, task-specific tools appear on the Desktop right when you need them and show only the currently possible and necessary actions. This helpful user convenience removes uncertainty from model building and brings order to simulations.

ZINK Imaging, the inventor of the ZINK Technology and the manufacturer of ZINK Paper™ -- a revolutionary approach to full-color printing of information and images with unparalleled simplicity -- makes frequent use of COMSOL Multiphysics within product invention, development, and manufacturing. Dr. Bill Vetterling, Research Fellow and Director of the Image Science Lab at ZINK Imaging, attended the 2009 COMSOL Conference and tried out the new user interface. "The version 4.0 prerelease that was made available to attendees was a great way to try out new features,” says Dr. Vetterling.

Current users with a COMSOL Multiphysics version 4.0 floating network license will be able to deploy across as many Windows HPC Server 2008 nodes as they choose, at no additional COMSOL Multiphysics licensing cost.

“By creating applications that run on Windows HPC Server 2008, scientific and engineering software companies like COMSOL are helping speed discovery”, said Vince Mendillo, senior director, Microsoft High Performance Computing Group. “ Scientists, engineers and analysts need easy-to-use tools and accessible high performance computing power to create competitive advantage.”

COMSOL Multiphysics supports parallel processing through standard shared-memory multicore computers as well as distributed-memory clusters. Users can turn to clusters to solve a series of parameter steps for a model, one parameter per node, or they can solve a single large model using distributed memory. For maximum performance, the COMSOL cluster implementation can utilize shared-memory multicore processing on each node in combination with the MPI-based distributed memory model.
