LevelSetBiMaterialRankFour

Compute a RankFourTensor material property for bi-materials problem (consisting of two different materials) defined by a level set function.

Description

This material, LevelSetBiMaterialRankFour determines the global material property by switching the two Rank-4 tensor material properties with different base_name based on the level set values. See LevelSetBiMaterialReal for more information.

commentnote:Different Use Cases for AD and non-AD Versions

The non-AD version of this class is required to compute the contribution of the stress to the off-Jacobian entries. In an AD simulation, this term is not required.

The non-AD version of this class can be used to select between the Jacobian () computed by two ComputeStress materials that are defined for the level set positive domain and negative domain respectively, based on the sign of the level set field. The AD version of this class can be used to determine other Rank-4 quantities, such as the elasticity tensor (C)

  • constant_onNONEWhen ELEMENT, MOOSE will only call computeQpProperties() for the 0th quadrature point, and then copy that value to the other qps.When SUBDOMAIN, MOOSE will only call computeQpProperties() for the 0th quadrature point, and then copy that value to the other qps. Evaluations on element qps will be skipped

    Default:NONE

    C++ Type:MooseEnum

    Options:NONE, ELEMENT, SUBDOMAIN

    Controllable:No
