Magnetic Flux Conservation
The Magnetic Flux Conservation node adds Equation 5-5 above (or a similar equation depending on the selected constitutive relation) for the magnetic potential and provides an interface for defining the constitutive relation and the relevant material properties (for example, the relative permeability).
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 Nonsolid 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.
Constitutive Relation b-H
See the settings for Constitutive Relation B-H under Ampère’s Law, except for these differences:
•
Magnetic losses and Effective B-H curve, being time-harmonic material models, are not available.
•
Select B-H curve to use a curve that relates magnetic flux density B and the magnetic field H as |B| =f (|H|). To define |B|, select From material (the default) to use the value from the material or select User defined to specify a value or expression for the magnitude of the magnetic flux density in the field that appears.
