I do not have the knowledge if the Frozen Permeability Method (FP) is implemented in MAXWELL as a tool or package.....If so, what is the procedure for its use?
You can map the non-linear permeability at a certain design point from Magnetostatic solver to Eddy current solver, and freeze permeability in Eddy current solver. This include both apparent and incremental permeability. More explanation and the procedure to do it can be found at:
