LinearFVDirichletCHTBC
Description
This object is a boundary condition used in the Navier-Stokes module that can be used for conjugate heat transfer (CHT) problems. Its role is to enforce a fixed Dirichlet value at an interface where heat is exchanged between solid and fluid regions. In practice, it is a wrapper around LinearFVAdvectionDiffusionFunctorDirichletBC with additional content allowing error checking in CHT applications. For more information on the design of CHT, see the CHT capability page.

Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.

Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.
- implicitTrueDetermines whether this object is calculated using an implicit or explicit form
Default:True
C++ Type:bool
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form
- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).
