COMSOL is the makers of COMSOL Multiphysics (formerly called FEMLAB), a multiphysics modeling software for engineering simulation and virtual prototyping in application areas such as fuel cells, MEMS, CFD, chemical reactions, electromagnetics, and structural mechanics. COMSOL Multiphysics provides a complete FEA package with a unique equation-based modeling approach that allows for fully coupled multiphysics modeling in 2D and 3D. COMSOL Multiphysics may also be run with Matlab if desired.
