COMSOL releases model 6.2 of COMSOL Multiphysics

COMSOL has introduced the discharge of COMSOL Multiphysics model 6.2, including various data-driven mannequin performance for highly effective standalone simulation purposes and multiphysics-based digital twins.

In response to the corporate, it additionally options high-performance multiphysics solvers for electrical motor evaluation, as much as 40% sooner turbulent CFD simulations, and orders of magnitude sooner impulse response calculations for room and cabin acoustics. As well as, it’s now as much as seven occasions sooner to carry out boundary aspect evaluation (BEM) of acoustics and electromagnetics when working on units.

The corporate says the surrogate fashions present correct simulation outcomes sooner than full finite aspect fashions that approximate them. When utilized in simulation purposes, it produces near-instantaneous outcomes, offering app customers with an enhanced interactive expertise. As well as, surrogate fashions are helpful for digital twins, the place quick and frequent updates of simulation outcomes are sometimes vital.

The newest model of the software program additionally introduces the power to create simulation purposes with computerized updates by way of timer occasions, which COMSOL says could possibly be helpful when creating digital twins or simulation purposes linked to the Web of Issues.

“Different fashions considerably improve the applying constructing capabilities of COMSOL Multiphysics®, and open new prospects for our customers,” says Lars Langmeier, COMSOL Chief Scientist. “They’ll now create highly effective digital twins and create autonomous purposes which are interactive, computationally quick, and correct.”

Excessive-performance multiphysics simulation of electrical motors

Model 6.2 expands the highly effective simulation capabilities of electrical motors in addition to transformers and different electrical machines with a time interval analyzer, obtainable within the AC/DC module. It additionally allows multi-physics kinematic evaluation involving acoustics, structural mechanics, multi-body dynamics, and warmth switch, and makes it potential to carry out optimization research to search out new engine designs.

“The brand new resolution technique makes an necessary class of electrical motor simulations a number of orders of magnitude sooner,” says Durk de Vries, technical product supervisor for AC/DC module at COMSOL. “It permits environment friendly evaluation of multi-physics phenomena that have been beforehand out of attain. That is pivotal for optimizing electrical motor design, the place a stability between structural, thermal and electromagnetic targets is important.”

As well as, core choices, comparable to visualization and linking, have been improved, and extra merchandise have been expanded and up to date, the corporate says. Model 6.2 additionally provides greater than 100 new and up to date fashions, serving to customers enhance their modeling expertise.

Some highlights from the expanded scope of physics modeling embrace:

• 7 turbulent fashions for move at excessive Mach numbers
• Lifelike frequency-based textures for simulating acoustics within the time area
• Modeling of hydrogen embrittlement in stable supplies for gasoline cells, electrolyzers, and corrosion
• Prolonged injury, fractures, and make contact with modeling
• Consumer-friendly particular absorption calculations for RF tissue simulation
• Evaluation of sunshine propagation by way of liquid crystals
• Capability to make use of native climate knowledge for temperature and stress in simulations, primarily based on GPS location
• The boundary aspect technique, used right here to calculate the radar cross part, is now as much as 7 occasions sooner.
