Rank Four Aux
Access a component of a RankFourTensor
Description
The AuxKernel RankFourAux is used to save single components of Rank-4 tensors into an AuxVariable for visualization and/or post-processing purposes, similar to the functionality provided by RankTwoAux for Rank-2 tensors RankFourAux is commonly used to output components of the elasticity (or stiffness) tensor, , in mechanics simulations.
The RankFourAux takes as arguments the values of the index_i, index_j, index_k, and index_l for the single Rank-4 tensor component to save into an AuxVariable. (1) Eq. (1) shows the index values for a linear hyperelastic stiffness tensor with 21 independent material parameters; the various available elasticity tensor symmetry options is discussed in the material ComputeElasticityTensor documentation.
Example Input File Syntax
[./matl_C25]
type = RankFourAux
rank_four_tensor = elasticity_tensor
index_i = 1
index_j = 1
index_k = 0
index_l = 2
variable = C25
[../]
An AuxVariable is required to store the RankFourAux AuxKernel information. Note that the name of the AuxVariable is used as the argument for the variable input parameter in the RankFourAux block.

Unit:(no unit assumed)
Controllable:No
Description:The list of blocks (ids or names) that this object will be applied
- boundaryThe list of boundaries (ids or names) from the mesh where this object applies

Unit:(no unit assumed)
Controllable:No
Description:The list of boundaries (ids or names) from the mesh where this object applies
- check_boundary_restrictedTrueWhether to check for multiple element sides on the boundary in the case of a boundary restricted, element aux variable.
