HFSS15: Defining Anisotropic Relative Permeability Tensors

If the material property is anisotropic, its characteristics are defined by its anisotropy tensor. You must define three diagonals for anisotropic permeability. Each diagonal represents a tensor of your model along an axis.

These tensors are relative to the coordinate system specified as the object’s Orientation property. By specifying different orientations, several objects can share the same anisotropic material but be oriented differently.

1. In the Relative Permeability row in the View/Edit Material window, select Anisotropic from the Type pull-down list.

Three rows named T(1,1), T(2,2) and T(3,3) are added below the Relative Permeability row.

2. Enter the relative permeability along one axis of the material’s permeability tensor in the Value box of the T(1,1) row.

3. Enter the relative permeability along the second axis in the Value box of the T(2,2) row.

4. Enter the relative permeability along the third axis in the Value box of the T(3,3) row.

If the relative permeability is the same in all directions, use the same values for each axis.

These values can also be defined as variables.
