The Ampère’s Law, Magnetostrictive node adds Ampère’s law for the magnetic field in a magnetostrictive material and provides an interface for defining the electric properties. It is normally used as part of
Magnetostriction multiphysics interface together with a
Magnetostriction multiphysics coupling node and
Magnetostrictive Material node in the corresponding
Solid Mechanics interface.
Ampère’s Law, Magnetostrictive node is added by default to the
Magnetic Fields interface when adding a Magnetostriction multiphysics interface. The interface requires the AC/DC Module and at least one of the following modules: Structural Mechanics, MEMS, Acoustics.
The default Relative permittivity εr (dimensionless) for the media is used
From material and defined on the shell domain. 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.
Mr is the remanent magnetization (SI unit: A/m). Enter
X and
Y components.
