GapConductanceConstant

Description

The GapConductanceConstant material provides a user-specified, constant gap conductance that is used in thermal contact enforcement. This material model is typically not directly specified by the user, but is created using the ThermalContactAction, the details of which are documented in the ThermalContact system documentation page.
