- boundaryThe list of boundary IDs from the mesh where this object applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundary IDs from the mesh where this object applies
- temperatureThe name of the temperature functor
C++ Type:MooseFunctorName
Controllable:No
Description:The name of the temperature functor
FunctorGapFluxModelRadiation
Gap flux model for heat transfer across a gap due to radiation, based on the diffusion approximation. Uses a temperature functor.
Description
FunctorGapFluxModelRadiation implements the same equations as GapFluxModelRadiation, however, it uses the functor system to evaluate needed quantities on-the-fly. The functor system is leveraged heavily by MOOSE's finite volume discretizations. To use pre-initialized data, which is the tradition for finite element discretizations, the GapFluxModelRadiation object may be the more appropriate object to use.
Example Input File Syntax
[radiation]
type = FunctorGapFluxModelRadiation
temperature = temp
boundary = 100
primary_emissivity = 1.0
secondary_emissivity = 1.0
[]
FunctorGapFluxModelRadiation must be used in conjunction with the modular gap conductance constraint as shown below:
[ced]
type = ModularGapConductanceConstraint
variable = lm
secondary_variable = temp
primary_boundary = 100
primary_subdomain = 10000
secondary_boundary = 101
secondary_subdomain = 10001
gap_flux_models = 'radiation conduction'
ghost_higher_d_neighbors = true
[]

Optional 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
C++ Type:bool
Controllable:No
Description:In 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).
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.
- execution_order_group0Execution order groups are executed in increasing order (e.g., the lowest number is executed first).
