COMSOL releases version 6.3 of COMSOL Multiphysics

The new version includes automated geometry preparation tools, GPU support for accelerated acoustics simulation, and surrogate model training, a new Electric Discharge Module, and an interactive Java environment, to name a few.

The new automated geometry preparation tools streamline model development by removing unnecessary details and defects in CAD models, resulting in higher-quality meshes for enhanced simulation reliability. Users can thereby import larger industrial CAD models, which originally were not meant for simulation, and use the automated geometry preparation tools to make the necessary adjustments for robust 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.

Up to 25x faster transient acoustics simulations

The Acoustics Module now offers GPU support for up to 25x faster simulations of pressure acoustics in the time domain, along with new capabilities for poroacoustics, including support for modelling 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 optimising acoustics in office and residential spaces," said 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."

Detailed electric discharge and breakdown simulations

The release of COMSOL Multiphysics version 6.3 also introduces the Electric Discharge Module, which offers powerful simulation capabilities spanning a wide range of electric discharge scenarios, including atmospheric pressure gas discharges, breakdown phenomena in liquids like transformer oil, and solid materials like insulating polymers.

"The Electric Discharge Module makes new modelling capabilities available that aid in the design of anything from consumer electronics to high-voltage systems," said 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. Discharge phenomena involve multiple physics and are really suited for the full potential of COMSOL’s modelling tools."
