COMSOL Releases Version 6.2 of COMSOL Multiphysics, adding Surrogate Model Functionality

COMSOL, a simulation software company, has released COMSOL Multiphysics version 6.2.

This latest version introduces data-driven surrogate model functionality, which enhances the efficiency of standalone simulation apps and multiphysics-based digital twins. The software also features high-performance multiphysics solvers for the analysis of electric motors, offers up to 40% faster turbulent CFD simulations, and delivers 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.

Surrogate models, which deliver accurate simulation results much faster than the full-fledged finite element models that they approximate, are a key feature of the new software. These models are particularly useful in simulation apps and digital twins, where fast and frequent updates of simulation results are often necessary.

“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.”

Version 6.2 also expands the capabilities for efficient simulation of electric motors, transformers, and other electric machinery through a time periodic solver, available in the AC/DC Module.

“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.”

The latest version of COMSOL Multiphysics also introduces new modeling features across the board, including improved visualization and meshing, expanded and updated add-on products, and more than 100 new and updated example models.

COMSOL Multiphysics, COMSOL Server, and COMSOL Compiler software products are supported on Windows, Linux, and macOS operating systems.

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
