![]() ![]() “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. 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. 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 much faster than the full-fledged finite element models that they approximate. Effective simulation apps and digital twins Turbulent flow simulations are now up to 40% faster, showcased here by high-Mach-number flow through a ramjet nozzle. ![]() Additionally, it is now up to 7 times faster to perform boundary element analysis (BEM) for acoustics and electromagnetics when running on clusters. 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. 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.
