COMSOL Multiphysics v6.2 Released

BURLINGTON, MA, USA, Nov 9, 2023 — 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,” says 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,” says 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:

  • 7 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
The boundary element method, used here for a radar cross section computation, is now up to 7 times faster.

The latest version of COMSOL Multiphysics solidifies its standing as a comprehensive multiphysics simulation software, offering unmatched physics modeling and simulation capabilities within a single software environment. It also enhances its support for building, maintaining, and compiling standalone simulation apps, thereby extending the use of simulation to individuals beyond the modeling and simulation community.
