| The initial configuration of a Nd3Fe14B platelet. The mesh is initially refined around the domain wall. | Due to an external applied field the domain wall starts to move. | As the domain wall reaches the coarse mesh, it "collapses". | |
| Refinement at the new position and coarsening at the previous position of the domain wall allows the domain wall to move on. The magnetization at the newly inserted nodes is calculated on a small window of the FE mesh. [3, 4, 5] |  |
