In addition, core offerings, like visualization and meshing, have been improved, and add-on products are expanded and updated, the company says. This is pivotal for electric motor design optimization, where a balance between structural, thermal, and electromagnetic objectives is essential.” ![]() “It allows for efficient analysis of multiphysics phenomena that were previously out of reach. “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 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. 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. “They can now create effective digital twins and build interactive, computationally fast, and accurate standalone apps.” High-Performance Multiphysics Simulations for Electric Motors “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. The latest software version also introduces the ability to make simulation apps with automated updates through timer events, which COMSOL says can useful when creating digital twins or IoT-connected simulation apps. In addition, surrogate models are useful for digital twins, where fast and frequent updates of simulation results are often necessary. When used in simulation apps, this leads to near-instantaneous results, providing app users with an improved interactive experience. Surrogate models deliver accurate simulation results faster than the full-fledged finite element models that they approximate, the company says. Additionally, it is now up to seven times faster to perform boundary element analysis (BEM) for acoustics and electromagnetics when running on clusters. 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.Īccording to the company, 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. ![]()
