Comsol Multiphysics 6.3 (290)

COMSOL, a global leader in modeling and simulation software, has announced the release of COMSOL Multiphysics version 6.3, which delivers new features and capability updates for efficient physics modeling and simulation app development. 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 modeling anisotropic materials and frequency-dependent material properties in the time domain.

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.
