INSADMomentumCoupledForce

This object adds a term to the incompressible momentum equation directly proportional to a coupled vector variable coupled_vector_var or a vector function vector_function. Positive coupled variable or function components represent momentum sources in that component direction, e.g. if the x-component is positive then this object imposes a momentum source in the +x direction.

Input Parameters

  • variableThe name of the variable that this Kernel operates on

    C++ Type:NonlinearVariableName

    Options:

    Description:The name of the variable that this Kernel operates on

Required Parameters

  • blockThe list of block ids (SubdomainID) that this object will be applied

    C++ Type:std::vector

    Options:

    Description:The list of block ids (SubdomainID) that this object will be applied

  • coupled_vector_varThe coupled vector variable applying the force. Positive variable components represent momentum sources in that component direction, e.g. if the x-component is positive then this object imposes a momentum source in the +x direction. Multiple variable names can be provided; the result will be a summed force.

    C++ Type:std::vector

    Options:

    Description:The coupled vector variable applying the force. Positive variable components represent momentum sources in that component direction, e.g. if the x-component is positive then this object imposes a momentum source in the +x direction. Multiple variable names can be provided; the result will be a summed force.

  • displacementsThe displacements

    C++ Type:std::vector

    Options:

    Description:The displacements

  • vector_functionA vector function which can be used to stand-in for the 'coupled_vector_var' param. Multiple function names can be provided; the result will be a summed force

    C++ Type:std::vector

    Options:

    Description:A vector function which can be used to stand-in for the 'coupled_vector_var' param. Multiple function names can be provided; the result will be a summed force

Optional Parameters

  • control_tagsAdds user-defined labels for accessing object parameters via control logic.

    C++ Type:std::vector

    Options:

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • diag_save_inThe name of auxiliary variables to save this Kernel's diagonal Jacobian contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

    C++ Type:std::vector

    Options:

    Description:The name of auxiliary variables to save this Kernel's diagonal Jacobian contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    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

    Options:

    Description:Determines whether this object is calculated using an implicit or explicit form

  • save_inThe name of auxiliary variables to save this Kernel's residual contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

    C++ Type:std::vector

    Options:

    Description:The name of auxiliary variables to save this Kernel's residual contributions to. Everything about that variable must match everything about this variable (the type, what blocks it's on, etc.)

  • seed0The seed for the master random number generator

    Default:0

    C++ Type:unsigned int

    Options:

    Description:The seed for the master random number generator

  • 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

    Options:

    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.
