COMSOL Version 6.3 Officially Available

COMSOL has officially released COMSOL Multiphysics®version 6.3, offering new features and capability updates for physics modeling and simulation app development. The new version, according to COMSOL, includes automated geometry preparation tools, graphics processing unit (GPU) support for accelerated acoustics simulation and surrogate model training, a new Electric Discharge Module, and an interactive Java environment, and more.

The new automated geometry preparation tools streamline model development by removing unnecessary details and defects in CAD models, COMSOL notes. Users can mport larger industrial CAD models that originally were not meant for simulation and use the automated geometry preparation tools to make adjustments for simulations. The interactive Java environment allows for on-the-fly model modifications using the COMSOL API. Additionally, a chatbot tool is available to assist with Java coding and answer general queries.

Faster Transient Acoustics Simulations

The Acoustics Module now offers GPU support for faster simulations of pressure acoustics in the time domain, along with new capabilities for poroacoustics, including support for modeling anisotropic materials and frequency-dependent material properties in the time domain.

“The new GPU support for transient acoustic simulations is invaluable for engineers working on automotive sound systems or optimizing acoustics in office and residential spaces,” says Mads J. Herring Jensen, development manager at COMSOL. “Being able to produce acoustics simulations much faster will help our users to ultimately develop new design iterations and product innovations more quickly as well.”

Electric Discharge and Breakdown Simulations

COMSOL Multiphysics version 6.3 also introduces the Electric Discharge Module, which offers simulation capabilities spanning a range of electric discharge scenarios. 

“The Electric Discharge Module makes new modeling capabilities available that aid in the design of anything from consumer electronics to high-voltage systems,” says Lipeng Liu, technical product manager at COMSOL. “Electric discharge simulation has been a high priority for us, and it is rewarding to see COMSOL's multiphysics strengths come together in this product.”

Across the Product Suite

Additional highlights of COMSOL Multiphysics version 6.3 include:

• Efficient data sampling for surrogate model creation
• Electromechanical modeling for thin structures, tools for moisture-induced swelling and simplified workflows for spot welds and fasteners
• More accurate electrostatic force calculations for MEMS devices, modeling of laminated iron in motors and transformers, and easier modeling of periodic structures in wave optics
• Incorporation of Reynolds-stress turbulence models, non-Newtonian flow in porous media, and fast drying simulations with nonequilibrium moisture transport
• Precipitation and crystallization simulation for particle nucleation and growth with particle size distribution
