Default Comsol Multiphysics v5.3




Comsol Multiphysics v5.3 | 4.1 GB




COMSOL, the leading provider of multiphysics modeling and simulation software, has released version 5.3 of COMSOL Multiphysics software, is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. This release provides you with notable performance improvements as compared to earlier versions.
You will experience speedup by a factor of up to ten in software responsiveness, as well as new and improved features for solving, meshing, and the physics-based add-on modules. Version 5.3 makes it more efficient to create models and deploy and run apps.

RELEASE NOTES
