Simulation software provider (Burlington, Mass., U.S.) has released version 6.2 of Comsol Multiphysics, a software is well-suited to . The company has added data-driven surrogate model functionality for efficient standalone simulation apps and multiphysics-based digital twins. The updated version 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 able to more rapidly perform boundary element analysis (BEM) for acoustics and electromagnetics when running on clusters.

Surrogate models deliver accurate simulation results faster than the full-fledged finite element models that they approximate, Comsol explains. 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.

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. More efficient analysis of multiphysics phenomena “is pivotal for electric motor design optimization, where a balance between structural, thermal, and electromagnetic objectives is essential,” notes Durk de Vries, technical product manager for the AC/DC Module at Comsol.

Users will also 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.
