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.

Input File Usage

ELECTRICAL CONDUCTIVITY, TYPE=ISOTROPIC

Orthotropic Electrical Conductivity

For orthotropic electrical conductivity three values of electrical conductivity (σ11E, σ22E, σ33E) are needed at each temperature and field variable value.

Input File Usage

ELECTRICAL CONDUCTIVITY, TYPE=ORTHOTROPIC

Anisotropic Electrical Conductivity

For fully anisotropic electrical conductivity six values (σ11E, σ12E, σ22E, σ13E, σ23E, σ33E) are needed at each temperature and field variable value.

Frequency-Dependent Electrical Conductivity

Electrical conductivity can be defined as a function of frequency in an eddy current analysis.
