Adaptive mesh refinement of finite element meshes significantly improves the solution of 3D micromagnetic calculations and optimizes the number of unknowns. In dynamic simulations domain wall movement requires partial refinement and coarsening. The windowing technique is applied to obtain a better solution at the newly inserted elements. Nucleation sites of reverse domains can be detected and the grid suitably refined.
