Material Tensor Integral

This postprocessor computes an element integral of a component of a material tensor as specified by the user-supplied indices

Description

The MaterialTensorIntegral postprocessor computes the volume integral of the Rank-2 tensor component specified by the user. (1) where is the computed volume integral quantity and is the tensor component selected by the user. The tensor component indicies, and , range from 0 to 2 as shown in the reference tensor (2)

This class is most often used in Generalized Plane Strain simulations to calculate the out-of-plane stress component.

Optional Parameters

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    Description:Set the enabled status of the MooseObject.

  • 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).

  • use_displaced_meshTrueWhether 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.
