*ELECTRICAL RESISTIVITY

Specify electrical resistivity.

This option is used to define electrical resistivity for elements that support the electric potential degree of freedom in a coupled thermal-electrical, coupled thermal-electrical-structural, coupled thermal-electrochemical, coupled thermal-electrochemical-structural, or coupled thermal-electrochemical-structural-pore pressure analysis.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variables included in the definition of electrical resistivity. If this parameter is omitted, the electrical resistivity is assumed not to depend on any field variables but may still depend on temperature. See Material Data Definition for more information.

TYPE

Set TYPE=ISOTROPIC (default) to define isotropic electrical resistivity.

Set TYPE=ORTHOTROPIC to define orthotropic electrical resistivity.

Set TYPE=ANISOTROPIC to define fully anisotropic electrical resistivity.

Data lines to define isotropic electrical resistivity (TYPE=ISOTROPIC)

First line

  1. Electrical resistivity. (Units of C-1TL φ .)

  2. Temperature.

  3. First field variable.

  4. Second field variable.

  5. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)

  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define isotropic electrical resistivity as a function of temperature and field variables.

Data lines to define orthotropic electrical resistivity (TYPE=ORTHOTROPIC)

First line

  1. ρ 11 E . (Units of C-1TL φ .)

  2. ρ 22 E .

  3. ρ 33 E .

  4. Temperature.

  5. First field variable.

  6. Second field variable.

  7. Etc., up to four field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four)

  1. Fifth field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define orthotropic electrical resistivity as a function of temperature and field variables.
