FVFunctorDirichletBC

Description

FVFunctorDirichletBC will specify the value of a field at the boundary. The value will be determined by a Functor.

commentnote

This boundary condition will only accept regular functors. ADFunctors (such as variables) must be converted to regular functors using a FunctorADConverter.

Example Syntax

In this example the functor, a constant value of 10, is defined using a GenericFunctorMaterial.

[Materials]
  [bc_value]
    type = GenericFunctorMaterial
    prop_names = bc_value
    prop_values = 10

[FVBCs]
  [left]
    type = FVFunctorDirichletBC
    variable = u
    boundary = left
    functor = bc_value
  []
  [right]
    type = FVDirichletBC
    variable = u
    boundary = right
    value = 0

Input Parameters

  • 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

  • functorThe name of the functor whose value is imposed on the boundary. A functor is any of the following: a variable, a functor material property, a function, a post-processor, or a number.

    C++ Type:MooseFunctorName

    Controllable:No

    Description:The name of the functor whose value is imposed on the boundary. A functor is any of the following: a variable, a functor material property, a function, a post-processor, or a number.

  • variableThe name of the variable that this boundary condition applies to

    C++ Type:NonlinearVariableName

    Controllable:No

    Description:The name of the variable that this boundary condition applies to

Required Parameters

  • displacementsThe displacements

    C++ Type:std::vector<VariableName>

    Controllable:No

    Description:The displacements

  • functor_only_defined_on_other_sideFalseWhether to evaluate the functor on the other side of the boundary. Note that depending on the functor type, this may require the 'ghost_layers' parameter to be set. For a FV variable with two term expansion, three ghost layers are needed.

    Default:False

    C++ Type:bool

    Controllable:No

    Description:Whether to evaluate the functor on the other side of the boundary. Note that depending on the functor type, this may require the 'ghost_layers' parameter to be set. For a FV variable with two term expansion, three ghost layers are needed.

  • ghost_layers0Number of ghost layers needed

    Default:0

    C++ Type:unsigned int

    Controllable:No

    Description:Number of ghost layers needed

Optional Parameters

  • absolute_value_vector_tagsThe tags for the vectors this residual object should fill with the absolute value of the residual contribution

    C++ Type:std::vector<TagName>

    Controllable:No

    Description:The tags for the vectors this residual object should fill with the absolute value of the residual contribution

  • extra_matrix_tagsThe extra tags for the matrices this Kernel should fill

    C++ Type:std::vector<TagName>

    Controllable:No

    Description:The extra tags for the matrices this Kernel should fill

  • extra_vector_tagsThe extra tags for the vectors this Kernel should fill

    C++ Type:std::vector<TagName>

    Controllable:No

    Description:The extra tags for the vectors this Kernel should fill

  • matrix_tagssystemThe tag for the matrices this Kernel should fill

    Default:system

    C++ Type:MultiMooseEnum

    Options:nontime, system

    Controllable:No

    Description:The tag for the matrices this Kernel should fill

  • vector_tagsnontimeThe tag for the vectors this Kernel should fill

    Default:nontime

    C++ Type:MultiMooseEnum

    Options:nontime, time

    Controllable:No

    Description:The tag for the vectors this Kernel should fill

Tagging 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: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

  • use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:False

    C++ Type:bool

    Controllable:No

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
