GapFluxModelConduction
Gap flux model for varying gap conductance using a coupled variable for temperature
Description
GapFluxModelConduction computes a conductive heat flux across a gap following the existing implementation of radiation physics. It is used by ModularGapConductanceConstraint.md.
The user is required to select the appropriate gap_geometry_type parameter (PLATE, CYLINDER, or SPHERE) for the model geometry in ModularGapConductanceConstraint.md. Two-dimensional Cartesian geometries are not restricted to be in or parallel to the X-Y coordinate plane.
Input Parameters
- allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
Default:False
