COMSOL Multiphysics® version 6.3 introduces significant enhancements to its geometry handling capabilities, streamlining the modeling process for both academic researchers and industry professionals. These updates include automatic geometry cleanup, a new virtual operation for merging faces, and the ability to add virtual operations in geometry parts and plane geometries. These features are designed to simplify complex geometries, improve meshing quality, and enhance overall simulation efficiency.
Automatic Geometry Cleanup
The automatic geometry cleanup feature in COMSOL Multiphysics® 6.3 identifies and removes small details and gaps within a model, preparing it for meshing and reducing simulation size. This process detects features such as sliver faces, short edges, narrow gaps, and thin domains, which are then eliminated to facilitate analysis. For users requiring more control, the optional Cleanup Wizard allows adjustment of detail sizes and selection of specific cleanup operations.
