FEELLGOOD is a micromagnetic solver using finite element technique to integrate Landau Lifshitz Gilbert equation. It computes the demagnetizing field using the so-called fast multipole algorithm.

It is developped by JC Toussaint & al. The code is being modified without any warranty it works. A dedicated website can be found here
