Unfortunately I observed that the postprocessing solver (MagnetoDynamicsCalcFields) has neglected the magnetization vector when the magnetization vector has been given in a material section or only elemental approximations have been calculated. This has now been corrected in the devel branch of the code repository. Now, when the magnetization vector M is given in either a material section or a body force section, the magnetic field strength H is always computed as H = v B - M.

Thus, if you don't update and recompile, a different magnetic field strength is calculated when the magnetization is moved from a material section to a body force section and the computation of nodal approximations is not prevented.
