	'''[[wikipedia:COMSOL_Multiphysics\|COMSOL]]''' (formerly FEMLAB) is a finite element analysis, solver and Simulation software / FEA Software package for various physics and engineering applications, especially coupled phenomena, or multiphysics. COMSOL Multiphysics also offers an extensive interface to MATLAB and its toolboxes for a large variety of programming, preprocessing and postprocessing possibilities. The packages are cross-platform (Windows, Mac, Linux, Unix). In addition to conventional physics-based user-interfaces, COMSOL Multiphysics also allows for entering coupled systems of partial differential equations (PDEs~~). The PDEs can be entered directly or using the so called weak form (see finite element method for a description of weak formulation~~).
