We present a framework for modeling the boundary-value problem (frequency driven) for homogeneous multiferroic material under the validity of post constraint and apply it to fundamental differential equation of electromagnetism in valid new regimes (boundary conditions for material with simultaneous electric and magnetic order). Three facets of the model are addressed, which explicitly respect the validity of post constraint of modern electromagnetism. First, AFM (antiferromagnetic) ordering and magneto electric coupling are explained. Second, the energetic anaysis of multiferroic is expressed for ferroic-electric ordering. Third, the conflict of fundamental differential electromagnetism in multiferroic material under explicit application of boundary condition is resolved.
