Comsol multiphysics was earlier called FEMLAB, an acronym for the Finite Element Modeling Laboratory. This is an advanced software package for modeling and simulation of any physical process you can describe with partial differential equations.
When I was lecturing the course FYS135 Electricity and Magnetism I used the following Comsol multiphysics exercises (all in
