COMSOL Multiphysics® Version 6.4
COMSOL, a global leader in modeling and simulation software, announced the release of COMSOL Multiphysics® version 6.4, which introduces new features, major performance improvements, and expanded capabilities for multiphysics modeling and simulation app development. The latest version includes greatly improved solver performance through the NVIDIA CUDA® direct sparse solver, NVIDIA cuDSS, for NVIDIA AI infrastructure, the new Granular Flow Module, and a new framework for time-explicit dynamic analysis.
In addition to these major updates, geometry, meshing, and visualization workflows in COMSOL Multiphysics® have been enhanced, and productivity has been further advanced through optional large language model (LLM)-assisted simulation. The Chatbot window now supports connections to GPT-5™, DeepSeek™, Google Gemini™, Anthropic Claude™, and other OpenAI API-compatible models, enabling interactive, model-aware assistance that combines COMSOL documentation with information from the active simulation.
