HSBoundarySpecifiedTemperature
This component is a heat structure boundary that applies Dirichlet boundary conditions.
Usage
The parameter "hs" specifies the name of the heat structure component, and "boundary" is a list of boundary names on the heat structure where the boundary condition is to be applied.
The parameter "T" specifies the temperature function to strongly impose on the boundary.
Input Parameters
- 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:No
Description:Set the enabled status of the MooseObject.
Advanced Parameters
Formulation
For Dirichlet conditions on the boundary , the temperature is set to a known temperature function :
