In coupled thermal-electrical analyses user subroutine GAPELECTR is used to define the electrical conductance between two surfaces as a function of their temperatures, the gap between them, and any field variables. The problem definition is the same as in the verification file ei22vsjc.inp (“Coupled thermal-electrical surface interaction,” Section 1.7.3), where the gap electrical conductance is defined directly on the data lines of the *GAP ELECTRICAL CONDUCTANCE option as a function of the average temperature.
