Specify the constitutive relation that describes the macroscopic properties of the medium (relating the magnetic flux density B and the magnetic field H) for a magnetostrictive material:

where is the material magnetization that depends on the magnetic field and mechanical stress, and Mr is the remanent magnetization vector (SI unit: A/m).

This section is described for the Current Conservation feature.

The default Relative permittivity εr (dimensionless) for the media is used From material. For User defined, select Isotropic, Diagonal, Symmetric, or Full based on the characteristics of the permittivity and then enter values or expressions in the field or matrix.
