Directional Dependence of Electrical Conductivity
Isotropic, orthotropic, or fully anisotropic electrical conductivity can be defined. For non-isotropic conductivity a local orientation for the material directions must be specified (Orientations).
Isotropic Electrical Conductivity
For isotropic electrical conductivity only one value of electrical conductivity is needed at each temperature and field variable value. Isotropic electrical conductivity is the default.
Orthotropic Electrical Conductivity
For orthotropic electrical conductivity three values of electrical conductivity (, , ) are needed at each temperature and field variable value.
Anisotropic Electrical Conductivity
For fully anisotropic electrical conductivity six values (, , , , , ) are needed at each temperature and field variable value.
