Line Material Rank Two Scalar Sampler

Compute a scalar property of a RankTwoTensor

Description

The postprocessor LineMaterialRankTwoScalarSampler is used to output common scalar quantities computed from Rank-2 tensors along a user-defined line in the mesh. The postprocessor computes the same set of scalar quantities as the AuxKernel RankTwoScalarAux; for a full list of the available scalar quantities refer to the RankTwoScalarAux page.

The user must supply the start and end points of the line along which the Rank-2 tensor scalar quantity should be tracked. Often this class is used to track stress or strain along an exterior or interior edge of the mesh.

Input Parameters

  • startThe beginning of the line

    C++ Type:libMesh::Point

    Description:The beginning of the line

  • propertyName of the material property to be output along a line

    C++ Type:std::vector

    Description:Name of the material property to be output along a line

  • endThe end of the line

    C++ Type:libMesh::Point

    Description:The end of the line

  • sort_byWhat to sort the samples by

    C++ Type:MooseEnum

    Description:What to sort the samples by

Required Parameters

  • scalar_typeA scalar to ouput

    C++ Type:MooseEnum

    Description:A scalar to ouput

  • direction0 0 1Direction vector

    Default:0 0 1

    C++ Type:libMesh::Point

    Description:Direction vector

  • _is_broadcastTrue

    Default:True

    C++ Type:bool

  • contains_complete_historyFalseSet this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation

    Default:False

    C++ Type:bool

    Description:Set this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation

  • point10 0 0Start point for axis used to calculate some cylinderical material tensor quantities

    Default:0 0 0

    C++ Type:libMesh::Point

    Description:Start point for axis used to calculate some cylinderical material tensor quantities

  • point20 1 0End point for axis used to calculate some material tensor quantities

    Default:0 1 0

    Description:End point for axis used to calculate some material tensor quantities

  • execute_onTIMESTEP_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:TIMESTEP_END

    C++ Type:ExecFlagEnum

    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.
