RectangleCutUserObject

Creates a UserObject for planar cuts on 3D meshes for XFEM

The RectangleCutUserObject defines the boundary of a rectangular cut for XFEM to make on a 3 dimensional mesh. The cut_data parameter is a vector of length twelve that defines the x, y , and z Real values of the four vertices that form the rectangular cut. The object calculates the midpoint of the rectangular cut and normal, and includes logic to determine if a given point is located within the cut plane.

Input Parameters

  • cut_dataVector of Real values providing cut information

    C++ Type:std::vector

    Options:

    Description:Vector of Real values providing cut information

Required Parameters

  • heal_alwaysFalseHeal previous cuts at every time step

    Default:False

    C++ Type:bool

    Options:

    Description:Heal previous cuts at every time step

  • 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

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    Description:Set the enabled status of the MooseObject.

  • 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.

  • 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.

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool

    Options:

    Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

  • seed0The seed for the master random number generator

    Default:0

    C++ Type:unsigned int

    Options:

    Description:The seed for the master random number generator

  • 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
