Ampère’s Law and Current Conservation
The Ampère’s Law and Current Conservation node adds Ampère’s law and the equation of continuity for the electric current. It provides an interface for defining the constitutive relations and their associated properties.
This feature can be overridden with an Ampère’s Law feature or a Coil feature, which are identical to the ones in the Magnetic Fields interface, removing the electric potential and the current conservation equation from the selected domains.
Material Type
The Material type setting decides how materials behave and how material properties are interpreted when the mesh is deformed. Select Solid for materials whose properties change as functions of material strain, material orientation and other variables evaluated in a material reference configuration (material frame). Select Non-solid for materials whose properties are defined only as functions of the current local state at each point in the spatial frame, and for which no unique material reference configuration can be defined. Select From material to pick up the corresponding setting from the domain material on each domain.
The Conduction Current and Magnetic Field settings are the same as Ampère’s Law for the Magnetic Fields interface. The Electric Field settings are the same as for Current Conservation for the Electric Currents interface.
