COMSOL Multiphysics 4.4 Update 1

COMSOL Multiphysics 4.4 Update 1 | 202.9 mb

COMSOL, Inc., a leading global provider of engineering simulation software, announced the release of COMSOL Multiphysics 4.4, the latest version of its powerful platform for the modeling and simulation of electrical, mechanical, fluid, and chemical applications.

This update corrects several bugs and stability issues in COMSOL 4.4. We recommend that you reapply the software update after installing new add-on products to an existing COMSOL 4.4 installation.
