Thin Low Permeability Gap
Use the Thin Low Permeability Gap boundary condition to model gaps in magnetic materials filled with another material with smaller relative permeability. This feature applies the condition
This boundary condition is only applicable on interior boundaries and pair boundaries.Use this boundary condition to model, for example, air gaps in magnetic circuits.
Thin Low Permeability Gap
The default Relative permeability μr (dimensionless) is taken From material. For User defined select Isotropic, Diagonal, Symmetric, or Full based on the characteristics of the relative permeability, and then enter a value or expression in the field or matrix.
Enter a Surface thickness ds (SI unit: m) for the gap. The default is 1 m.
