FreeFEM is a popular open-source finite element software. It is excellent for multiphysics because it allows you to write your own partial differential equations (PDEs). Pros: Highly flexible, great for advanced math. Cons: Script-based (no fancy "drag and drop" GUI). 2. Elmer FEM While there is no permanent "free version" of
Overall: 2/10 – COMSOL's "free license" is more of a marketing teaser than a usable tool. For real learning or work, use OpenFOAM, Elmer, or Ansys Student instead. It is excellent for multiphysics because it allows
