GAPELECTR

User subroutine to define electrical conductance between surfaces in a coupled thermal-electrical or a coupled thermal-electrical-structural analysis.

User subroutine GAPELECTR:

  • assumes that the electrical current flowing between the interface surfaces is modeled as J = σ g ( φ A - φ B ) , where J is the electrical current density flowing across the interface from point A (the secondary surface) to point B (the main surface), φ A and φ B are the electrical potential on opposite points of the surfaces, and σ g is the surface electrical conductance;

  • is used to define σg, providing much greater flexibility than direct gap electrical conductance definition in specifying the dependencies of σg (for instance, it is not necessary to define the gap electrical conductance as a function of the average of the two surfaces' temperatures and/or field variables);

  • will be called at the secondary nodes of a contact pair (About Contact Pairs in Abaqus/Standard) for which the gap electrical conductance is defined in a user subroutine; and

  • ignores any dependencies or data specified for the gap electrical conductance outside the user subroutine.
