LineSegmentLevelSetAux

Auxiliary Kernel that calcuates level set value using line segments' description.

Description

The LineSegmentLevelSetAux calculates level set values for an interface that is defined by a set of line segments(LineSegmentCutSetUserObject). Usually the value of level set at a given point is calculated as a signed distance of this point from the boundary of the interface, with the sign determined by whether x is inside the closed interface contour.

Example Input File Syntax

[./ls]
  type = LineSegmentLevelSetAux
  line_segment_cut_set_user_object = 'moving_line_segments'
  variable = ls
[../]
(modules/xfem/test/tests/moving_interface/phase_transition.i)

Input Parameters

    C++ Type:AuxVariableName

    Options:

    Description:The name of the variable that this object applies to

Required Parameters

  • line_segment_cut_set_user_objectName of GeometricCutUserObject that gives the line segments information.

    C++ Type:UserObjectName

    Options:

    Description:Name of GeometricCutUserObject that gives the line segments information.

  • execute_onLINEAR TIMESTEP_ENDThe 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.

    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

    C++ Type:std::vector

    Options:

    Description:The 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.
