MaterialRealVectorValueAux
Capture a component of a vector material property in an auxiliary variable.
Converting a field from the material system, here a component of a vector material property (MaterialRealVectorValueAux) or a vector valued functor (FunctorMaterialRealVectorValueAux), to a variable may be desirable for several reasons: to match the format expected by certain kernels, for lagging the field between time steps or for output/testing/debugging.
This is particularly useful to examine anisotropic material properties. For output purposes only, an alternative is to use the output_properties argument of the Material or specify output_material_properties in the parameters of the desired output type nested in the [Outputs] block.
commentnote
The AD system currently does not support auxiliary variables. If you convert material properties or functors, which do support automatic differentiation, to auxiliary variables, the derivatives will be ignored.
Example syntax
In this example, the MaterialRealVectorValueAux is being used to examine different cracking criteria for a smear cracking model.

Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No

- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.
- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).

# This test is to ensure that the smeared cracking model correctly handles finite
# rotation of cracked elements.
# This consists of a single element that is first subjected to tensile loading
# in the y-direction via a prescribed displacement. This loading is sufficiently
# high to crack the material in that direction, but not completely unload. The
# prescribed displacement is then reversed so that the element is returned to its
# original configuration.
# In the next phase of the analysis, this element is then rotated 90 degrees by
# prescribing the displacement of the bottom of the element. The prescribed
# displacement BC used to crack the element in the first phase is deactivated.
# Once the element is fully rotated, a new BC is activated on what was originally
# the top surface (but is now the surface on the right hand side) to pull in
# the x-direction.
# If everything is working correctly, the model should re-load on the original
# crack (which should be rotated along with the elemnent) up to the peak stress
# in the first phase of the analysis, and then continue the unloading process
# as the crack strains continue to increase. Throughout this analysis, there should
# only be a single crack, as manifested in the crack_flags variables.

# Test for frictional beam constraint.
#
# Using a simple L-shaped geometry with a frictional constraint at the
# corner between the two beams. The longer beam properties and loading is
# taken from an earlier beam regression test for static loading. The maximum
# applied load of 50000 lb should result in a displacement of 3.537e-3. Since
# the constraint is frictional with a low normal force (1.0) and coefficient
# of friction (0.05) and the short beam is much less stiff, the
# y-dir displacement of the long beam is still 3.537e-3. However, the y-dir
# displacement of the short beam increases until the force exceeds the
# frictional capacity which in this case is 0.05 and then remains constant
# after that point.

# This test is to ensure that the smeared cracking model correctly handles finite
# rotation of cracked elements.
# This consists of a single element that is first subjected to tensile loading
# in the y-direction via a prescribed displacement. This loading is sufficiently
# high to crack the material in that direction, but not completely unload. The
# prescribed displacement is then reversed so that the element is returned to its
# original configuration.
# In the next phase of the analysis, this element is then rotated 90 degrees by
# prescribing the displacement of the bottom of the element. The prescribed
# displacement BC used to crack the element in the first phase is deactivated.
# Once the element is fully rotated, a new BC is activated on what was originally
# the top surface (but is now the surface on the right hand side) to pull in
# the x-direction.
# If everything is working correctly, the model should re-load on the original
# crack (which should be rotated along with the elemnent) up to the peak stress
# in the first phase of the analysis, and then continue the unloading process
# as the crack strains continue to increase. Throughout this analysis, there should
# only be a single crack, as manifested in the crack_flags variables.

# taken from an earlier beam regression test for static loading. The maximum

(modules/solid_mechanics/test/tests/smeared_cracking/cracking_rotation.i)
# This test is to ensure that the smeared cracking model correctly handles finite
# rotation of cracked elements.
# This consists of a single element that is first subjected to tensile loading
# in the y-direction via a prescribed displacement. This loading is sufficiently
# high to crack the material in that direction, but not completely unload. The
# prescribed displacement is then reversed so that the element is returned to its
# original configuration.
# In the next phase of the analysis, this element is then rotated 90 degrees by
# prescribing the displacement of the bottom of the element. The prescribed
# displacement BC used to crack the element in the first phase is deactivated.
# Once the element is fully rotated, a new BC is activated on what was originally
# the top surface (but is now the surface on the right hand side) to pull in
# the x-direction.
# If everything is working correctly, the model should re-load on the original
# crack (which should be rotated along with the elemnent) up to the peak stress
# in the first phase of the analysis, and then continue the unloading process
# as the crack strains continue to increase. Throughout this analysis, there should
# only be a single crack, as manifested in the crack_flags variables.
