In case you're wondering Maxwell is a Finite Element Analysis package from Ansys for low frequency EM fields [1]. It looks quite neat. I never used it, but I worked for a competitor and we had something similar.

File under "unexpectedly interesting and cool". I'd never seen such good visualizations of magnetic fields before, or of the magnetization process.

Ansys is such a powerful range of software but the guides on all features are basically non existent. (The tutorials do not count).
