The COMSOL Multiphysics® version 6.2 introduced the capability to increase the computational speed of the simulation apps using data-driven surrogate models. This leads to a more interactive user experience and promotes the wider use of simulations within an organization. Furthermore, the new surrogate model framework enables the building of new types of standalone simulation apps and effective digital twins.
In the electromagnetic field, version 6.2 provides updates that include faster nonlinear motor and transformer simulations with time-dimension periodicity. Additionally, new options are available for acoustic, structural, multibody, heat transfer, and optimization analysis of electric motors. Dispersive material models have been added for tissue and dielectrics. Stranded conductors, such as litz wires, can also be modeled. The magnetic field simulations are now automatically stabilized, and the high-frequency analysis has been enhanced based on the boundary element method (BEM).
The software is now more efficient at handling chemical reactions in plasmas and offers a preview of semiconductor doping profiles before solving them. The new RF modeling options are also available for averaging specific absorption rates (SAR) over 1-g and 10-g sample sizes and the software now allows the modeling of light wave propagation through liquid crystals.
COMSOL Multiphysics® version 6.2 can perform faster multiphysics simulations of electric machinery with nonlinear materials and impulse response simulations for acoustics. CFD models now solve up to 40% faster. In chemical engineering applications, the new version includes functionality for simulating vapor–liquid interfaces, including 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.
