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.

Turbulent flow simulations are now up to 40% faster, showcased here by high-Mach-number flow through a ramjet nozzle.

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.

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.

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.

COMSOL Multiphysics version 6.2 introduces game-changing functionality for simulation apps and digital twins as well as faster solver technology. Users can now increase the computational speed of their simulation apps using data-driven surrogate models, leading to a more interactive user experience and promoting wider use of simulations within an organization. Furthermore, the new surrogate model framework makes it possible to build new types of standalone simulation apps and effective digital twins.

Multiphysics simulations of electric machinery with nonlinear materials as well as impulse response simulations for acoustics are faster by an order of magnitude or more. CFD models now solve up to 40% faster. In chemical engineering applications, the new version includes functionality for the simulation of vapor-liquid interfaces, including both condensation and vaporization processes. Users of the structural-mechanics-based products will see updated damage and fracture modeling capabilities, along with functionality for circuit board warpage computation and multibody dynamics analysis of electric motors.
