A material's electrical conductivity:
must be defined for “Coupled thermal-electrical analysis,” Section 6.7.3;
must be defined for “Fully coupled thermal-electrical-structural analysis,” Section 6.7.4;
must be used to define the electromagnetic response of a conductor for “Time-harmonic eddy current analysis,” Section 6.7.5;
can be linear or nonlinear (by defining it as a function of temperature);
can be isotropic, orthotropic, or fully anisotropic;
can be specified as a function of temperature and/or field variables; and
can be specified as a function of frequency for “Time-harmonic eddy current analysis,” Section 6.7.5.
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,” Section 2.2.5).
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.

Electrical conductivity can be defined as a function of frequency in an eddy current analysis.
| Input File Usage: | *ELECTRICAL CONDUCTIVITY, FREQUENCY |
| Abaqus/CAE Usage: | Frequency-dependent electrical conductivity is not supported in Abaqus/CAE. |
Electrical conductivity is active only in coupled thermal-electrical elements, coupled thermal-electrical-structural elements, and electromagnetic elements (see “Choosing the appropriate element for an analysis type,” Section 26.1.3).
