We're pleased to announce the release of COMSOL Multiphysics® version 6.4.

Highlights include:

  • Enhanced solver performance with the new NVIDIA CUDA® direct sparse solver (cuDSS) for NVIDIA® GPUs for single-physics and multiphysics simulation
  • Structural explicit dynamics including support for nonlinear materials, for simulating impacts, blasts, and drop tests
  • Granular Flow Module: a new product that can be used to simulate the motion and interaction of solid particles in bulk processes, for applications such as conveying, mixing, and additive manufacturing
  • Support for OpenAI API-compatible models within the Chatbot window
  • Improved workflows for geometry and meshing
