An anisotropic dielectric material is placed in an isotropic dielectric material.
A certain voltage is applied across the model.
The distributions of the electric field and the current density are solved.
Unless specified in the list below, the default conditions will be applied.

The vectors of the electric field are shown below.
Also shown are the vectors of the electric flux density.
These two types of vectors are not parallel due to the anisotropy.
The axes are oriented based on Block, but they can be oriented based on Air.
In that case, set Euler angle (0, 0, 45) in the Direction tab of the body attribute.
