COMSOL releases version 6.2 of COMSOL Multiphysics

By Leave a Comment

COMSOL announced the release of COMSOL Multiphysics version 6.2, adding data-driven surrogate model functionality for efficient standalone simulation apps and multiphysics-based digital twins.

It also features high-performance multiphysics solvers for the analysis of electric motors, up to 40% faster turbulent CFD simulations, and an order of magnitude faster impulse response calculations for room and cabin acoustics. Additionally, it is now up to 7 times faster to perform boundary element analysis (BEM) for acoustics and electromagnetics when running on clusters.

Effective simulation apps and digital twins

Surrogate models deliver accurate simulation results much faster than the full-fledged finite element models that they approximate. When used in simulation apps, this leads to near-instantaneous results, providing app users with an improved interactive experience. In addition, surrogate models are useful for digital twins, where fast and frequent updates of simulation results are often necessary.

The latest software version also introduces the ability to make simulation apps with automated updates through timer events, which is especially useful when creating digital twins or IoT-connected simulation apps.

“Surrogate models significantly strengthen the app-building capabilities in COMSOL Multiphysics and open up new possibilities to our users,” said Lars Langemyr, chief scientist at COMSOL. “They can now create effective digital twins and build interactive, computationally fast, and accurate standalone apps.”

High-performance multiphysics simulations for electric motors

Version 6.2 expands the capabilities for efficient simulation of electric motors as well as for transformers and other electric machinery through a time periodic solver, available in the AC/DC Module. It also enables multiphysics motor analysis involving acoustics, structural mechanics, multibody dynamics, and heat transfer, and makes it possible to run optimization studies to find new motor designs.

“The new solving method makes an important class of electric motor simulations several orders of magnitude faster,” said Durk de Vries, technical product manager for the AC/DC Module at COMSOL. “It allows for efficient analysis of multiphysics phenomena that were previously out of reach. This is pivotal for electric motor design optimization, where a balance between structural, thermal, and electromagnetic objectives is essential.”

Enhanced modeling capabilities across the product suite

In version 6.2, users will discover new modeling features across the board. Core offerings, like visualization and meshing, are improved, and add-on products are expanded and updated. Version 6.2 also adds more than 100 new and updated example models, helping users enhance their modeling skills.

Some highlights from the broadened scope of physics modeling include:

  • Seven turbulence models for high-Mach-number flow
  • Realistic frequency-dependent materials for acoustics simulations in the time domain
  • Modeling of hydrogen embrittlement in solids for fuel cells, electrolyzers, and corrosion
  • Extended damage, fracture, and contact modeling
  • Easy-to-use specific absorption computations for RF tissue simulations
  • Analysis of light propagation through liquid crystals
  • Ability to use local weather data for temperature and pressure in simulations, based on a GPS location

Multiphysics simulation guides project decisions at construction sites

By Leave a Comment

A leading global cement supplier provides its customers with a compiled multiphysics simulation application that predicts curing times for concrete casting at construction sites.

Heidelberg Materials, one of the world’s largest suppliers of building materials, is putting multiphysics simulation into the hands of contractors with a compiled simulation app called HETT22. The app enables Heidelberg Materials’ customers to use simulation to make informed decisions regarding cost-effective casting strategies at construction sites.

The app predicts curing times and accounts for variables that affect concrete strength and durability, such as time, temperature, material selections, and casting technique. Ambient temperatures have a major impact on the curing time, and the app was built to use site-specific weather forecasts to provide the best possible predictions.

The simulation app’s user interface shows the temperature and strength of a concrete casting. Image courtesy of COMSOL.

“We provide HETT22 to our customers because of the value it adds for them at each decision point of a concrete casting job,” said Tom Fredvik, technical manager at Heidelberg Materials’ Sement Norge. “We see it as a core part of our tech support offering.”

Heidelberg Materials engaged consultancy Deflexional to create HETT22 and its associated models. After building the models in the COMSOL Multiphysics software, Deflexional used the software’s Application Builder to turn the models into a custom app, which they compiled into a standalone app using COMSOL Compiler.

In just six months after launch, HETT22 was downloaded more than 1,100 times.

Simulation results guide preemptive adjustments

The app also features a menu of Heidelberg Materials’ cement materials for the user to choose from. The company offers its customers hundreds of potential concrete recipes, including supplementary cementitious materials to be mixed with the concrete. By predicting the effects of choices related to physical conditions, a construction team can use the app to better manage the economics and carbon footprint of each project.

“We wanted HETT22 to help users predict the behavior of concrete that they may not be familiar with,” said Mikael Westerholm, project manager at Heidelberg Materials’ Cement Sverige.

Sharing the power of simulation

The Application Builder in the COMSOL Multiphysics simulation software makes it easy for users to build and maintain their own apps and the COMSOL Compiler add-on product makes it possible to turn them into standalone executable files with just a click. The compiled apps can be distributed to anyone, even those without a COMSOL license.

“The app developed for Heidelberg Materials by Deflexional is a perfect example of how simulation apps extend the benefits of simulation beyond the simulation engineer,” said Per Backlund, sales and marketing manager at COMSOL. “The collaboration between the companies resulted in an app that contains crucial knowledge about concrete curing, packaged in an intuitive user interface. When we created the Application Builder and our products for deploying simulation apps, we envisioned that our users would create apps that are accessible to anyone, no matter their simulation background. This project aligns perfectly with our vision.”

Designing better ionization gauges for high-vacuum applications

By Leave a Comment

By Alan Petrillo, COMSOL

Semiconductor manufacturing, particle physics research, and other valuable processes occur in high-vacuum or ultra-high-vacuum (HV/UHV) conditions. To help develop a better ionization gauge for measuring pressure in HV/UHV environments, instrument manufacturer INFICON of Liechtenstein used multiphysics modeling to test and refine its impressive new design. The Ion Reference Gauge 080 (IRG080), shown in Figure 1, resulted from an international project coordinated by the European Metrology Programme for Innovation and Research (EMPIR) to develop a better tool for quantifying pressure in HV/UHV environments.

“At HV/UHV pressures, there are not enough particles to force a diaphragm to move, nor are we able to reliably measure heat transfer. This is where we use ionization to determine gas density and corresponding pressure,” said Martin Wüest, head of sensor technology at INFICON.

INFICON Ion Reference Gauge 080
Figure 1. INFICON used COMSOL’s Multiphysics modeling software to design the Ion Reference Gauge 080 to measure pressure in high-vacuum or ultra-high-vacuum applications. Image provided by INFICON.

The most commonly used HV/UHV pressure-measuring tool is a Bayard–Alpert hot-filament ionization gauge placed inside the vacuum chamber. The heart of this instrument consists of the filament (or hot cathode), the grid, and the ion collector. Its operation starts with supplying low-voltage electric current to the filament, causing it to heat up. As the filament becomes hotter, it emits electrons that are attracted to the grid, which is supplied with higher voltage. Some electrons flowing toward and within the grid will collide with any free-floating gas molecules circulating in the vacuum chamber. Electrons that collide with gas molecules form ions that flow toward the collector. This measurable ion current in the collector will be proportional to the density of gas molecules in the chamber.

“We can then convert density to pressure, according to the ideal gas law,” Wüest said. “Pressure will be proportional to the ion current divided by the electron current, divided by a sensitivity factor that is adjusted depending on what gas is in the chamber.”

While the operational principles of these devices are sound, their calibration is too easily compromised by routine use and handling. Along with their sensitivity to heat, the core components of a Bayard–Alpert gauge can become easily misaligned. This can introduce measurement uncertainty of 10 to 20% — an unacceptably wide range of variation.

The project team chose INFICON’s IE514 extractor-type gauge as the current best practice for ionization gauge design. Francesco Scuderi, an INFICON engineer specializing in simulation, used the COMSOL Multiphysics software to model the IE514.

“After constructing the model geometry and mesh, we set boundary conditions for our simulation,” said Scuderi. “We are looking to express the coupled relationship of electron emissions and filament temperature, which will vary from approximately 1400 to 2000° C across the length of the filament. This variation thermionically affects the distribution of electrons and the paths they will follow.” (Figure 2)

Figure 2. The IE514 simulation showed the filament temperature (left) and the electric potential surrounding the grid structure (right).

Next, the model was used to calculate the percentage of electrons that collide with gas particles. From there, ray tracing of the resulting ions was performed, tracing the ions’ paths toward the collector (Figure 3).

NFICON IE514 ray tracing models using COMSOL Multiphysics.
Figure 3. Ray tracing models showed the simulated paths of electrons (blue) and ions (red) in the IE514.

“We can then compare the quantity of circulating electrons with the number of ions and their positions. From this, we can extrapolate a value for ion current in the collector and then compute the sensitivity factor,” said Scuderi.

INFICON’s model did an impressive job of generating simulated values that closely aligned with test results from the benchmark prototype. This enabled the team to observe how changes to the modeled design affected key metrics, including ionization energy, the paths of electrons and ions, emission and transmission current, and sensitivity.

The end product of INFICON’s design process, the IRG080, incorporates many components as existing Bayard–Alpert gauges, but key parts look quite different. For example, the new design’s filament is a solid suspended disc, not a thin wire. The grid is no longer a delicate wire cage but made from stronger-formed metal parts. The collector now consists of two components: a single pin or rod that attracts ions and a solid metal ring that helps direct electron flow away from the collector and toward a Faraday cup. This arrangement, refined through ray tracing simulation, improves accuracy by better separating the paths of ions and electrons (Figure 4).

Figure 4. Shown here is a COMSOL model of the final IRG080 gauge.

INFICON built 13 prototypes that underwent evaluation by the project consortium. Testing showed that the IRG080 achieved the goal of reducing measurement uncertainty to below 1%. Regarding sensitivity, the IRG080 performed eight times better than the benchmark.

Of course, this success was not the team’s alone. INFICON benefited from its partners’ insights and support, and in turn, the broader scientific and manufacturing community will benefit from more consistent measurements of HV/UHV conditions.

COMSOL completes the working environment for modeling and simulation projects with the Model Manager Server

By Leave a Comment

COMSOL announces a major update to the COMSOL Multiphysics software version 6.0. The update builds out the Model Manager server with a web interface — an asset management system — to make it easier for COMSOL users and nonusers alike to manage models, simulation apps, and supplementary and auxiliary files.

COMSOL Multiphysics: from building models and apps to managing simulation projects
Through two decades of development, COMSOL Multiphysics evolved from a software that solved partial differential equations to one that defines the nature of multiphysics modeling: being able to build models with any combination of physics phenomena via the Model Builder. Thereby, engineers versed in the underlying physics and using software to build models began using COMSOL Multiphysics across technology-driven industries, academia, and research organizations for modeling and simulation. Next, COMSOL introduced the Application Builder and concept of simulation apps to expand the realm of who could access simulation to include those who had not traditionally been able to work with models and simulations.

Today, COMSOL completes the environment for managing modeling and simulation projects for product and process design through the recently introduced Model Manager and the Model Manager server with its accompanying asset management system.

About the Model Manager Server and its Asset Management System
Released in December 2021, the Model Manager allows you to:

–Search through models for particular parameter names and feature strings.
–Track model development through version control with model comparison and merging capabilities.
–Upload, link, and administrate supplementary and auxiliary files to a modeling and simulation or development project.

The model tree of a selected model can be previewed without opening the model.

The Model Manager has now been complemented by the Model Manager server’s asset management system, which is accessible through a web interface. In the asset management system, an asset can be considered as a container for links to your model versions, attached supplementary and auxiliary files, as well as various custom metadata fields. With the asset management system, you can itemize assets through model and app files, adding abstracts, setting permissions, and even include thumbnail images of the model at hand.

“As an extension of the COMSOL Multiphysics® simulation platform, the Model Manager server’s asset management system is useful for administrating and managing your models, apps, and simulations in a corporate network environment set up to your own liking,” says Sr. VP of Sales Phil Kinnane. “This could be project-based, model-based, team-based, or similar, according to how you want your organization to structure and organize such work.”

Clicking into an asset allows you to add files and metadata (abstract, thumbnail image, product requirements, etc.)

A collaborative environment to cover all elements of an organization
The Model Manager server is a database system that can be managed from either the COMSOL Desktop or a web-based UI. A local installation of any license type of COMSOL Multiphysics with the Model Manager and a local database is usually the initial step for a modeling engineer to acclimatize themselves to how this system can be best used within their organization. From there, full deployment can occur by installing the Model Manager server on a central server. Local installations of COMSOL Multiphysics can connect to the central server with the Model Manager server. “I think organizations will start by moving the tens and hundreds of COMSOL models they have been developing over the years to their asset management systems as a communal model library,” adds Kinnane. “Instead of chasing down the many engineers using the software for different purposes, they can now find and search through those models as a centralized repository instead.”

The full power of the Model Manager Server
COMSOL CTO Ed Fontes describes how the Model Manager server will take an organization’s simulation-driven project to the next level: “The true power of the Model Manager is not only in its ability to manage your simulation data, but in being able to version control and audit your actual model-building process.” He adds, “there are a number of simulation data management systems out there, but COMSOL has focused the Model Manager on the model-building process, such as to easily browse through the model tree of certain models or search for specific features like domain settings, boundary conditions, or study types to revisit, update, or even reuse.”

Internal or external customers may use the database system to keep track and use results from a project. They may also use simulation apps and provide feedback about their measurement and test data by uploading them and reports to the relevant asset. And, of course, contributors on the model development can also add their auxiliary data, such as CAD files and specifications, to the project. “In all,” says Fontes, “the Model Manager server and asset management system truly provide the complete working environment for modeling and simulation projects.”
