COMSOL Multiphysics is the industry standard for finite element analysis (FEA) and solving coupled physics phenomena — often called "multiphysics." Version 6.0 introduced significant improvements, including a new "Uncertainty Quantification Module" and the "Model Manager" for version control.
Because of its sophistication and commercial target audience (corporations, R&D labs), COMSOL is sold under paid licenses. The price for a single perpetual license with one module typically ranges from per year, depending on the configuration. Educational discounts exist but still require institutional purchase or enrollment. comsol multiphysics 6.0 free download
