DomainIntegralTopologicalQFunction

!syntax description /AuxKernels/DomainIntegralTopologicalQFunction

Description

This object is used to compute the value of the function used in the computation of fracture domain integrals, as described in FractureIntegrals. This form of the function is based on the mesh topology. Rings of elements in layers expanding from the crack front are formed, and the function varies from 1 to 0 from the inside nodes to the outside nodes of a given ring.

This object is not typically directly defined by a user, but is defined using the DomainIntegralAction block. Also, this object is used only for output purposes for debugging models, as the actual value of the function used in the computation is computed by the fracture domain integral Postprocessor objects.

Input Parameters

    C++ Type:UserObjectName

    Options:

    Description:The CrackFrontDefinition user object name

    Default:LINEAR TIMESTEP_END

    C++ Type:ExecFlagEnum

    Options:NONE INITIAL LINEAR NONLINEAR TIMESTEP_END TIMESTEP_BEGIN FINAL CUSTOM

    Description:The list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

  • boundaryThe list of boundary IDs from the mesh where this boundary condition applies

  • 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

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.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    Description:Set the enabled status of the MooseObject.

  • 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.
