Previous: Domain wall motion
Conclusions
- FEM is an efficient method to describe arbitrary geometries and irregular microstructures
- Locally highly non-uniform magnetisation distribution in hard magnetic materials
- Adaptive mesh refinement reduces the discretisation error
- Local refinement optimises the number of unknowns
- Partial coarsening allows dynamic magnetisation reversal
- The simulation of a model of a misoriented grain is in agreement with experimental observations
