*GAP ELECTRICAL CONDUCTANCE
Specify electrical conductance between surfaces.

This option is used to introduce gap electrical conductance in a surface interaction model in a coupled thermal-electrical or a coupled thermal-electrical-structural simulation. It must be used in conjunction with the *SURFACE INTERACTION option.

Product: Abaqus/Standard  

Type: Model data

Level: Model

Optional parameters:

DEPENDENCIES

Set this parameter equal to the number of field variables on which depends.

PRESSURE

Include this parameter to indicate that is a function of the contact pressure between the surfaces, p. Omit this parameter to define as a function of the clearance, d, between the surfaces.

USER

Include this parameter to define in user subroutine GAPELECTR. In this case the DEPENDENCIES parameter and any data lines are ignored.

Data lines to define the gap electrical conductance directly: 

First line:

  1. Electrical conductivity, . (Units of CT–1L–2–1.)

  2. Surface separation, d, or surface pressure, p.

  3. Average temperature, .

  4. Average value of the first field variable, .

  5. Average value of the second field variable, .

  6. Etc.

Repeat this data line as often as necessary to define the dependence of gap electrical conductance on the surface separation, average surface temperature, and the average of any predefined field variables on the surfaces.
