Tensor Mechanics Master Action System

Set up stress divergence kernels with coordinate system aware logic

The TensorMechanics Master Action is a convenience object that simplifies part of the mechanics system setup.

It applies to both the current kernel system based on the StressDivergenceTensors kernels and to the new kernel system based on the TotalLagrangianStressDivergence and UpdatedLagrangianStressDivergence kernels. Some options only apply to one or the other system, as outlined below.

It performs

  • Add StressDivergence Kernels (for the current coordinate system) – both systems, only Cartesian coordinates for the Lagrangian kernel system

  • Add WeakPlaneStress Kernel (for weak enforcement of the plane stress condition) – only the StressDivergenceTensors system

  • Add Strain calculation material (for the chosen strain model) – both systems

  • Correctly set use of displaced mesh – both systems

  • Optional: Setup of displacement variables (with the correct order for the current mesh) – both systems

  • Optional: Add AuxVariables and AuxKernels for various tensor components and quantity outputs – both systems

  • Optional: Set up out-of-plane stress/strain consistently – only the StressDivergenceTensors system

  • Optional: Automatic extraction of eigenstrain names from materials and correct application to proper blocks – both systems

  • Optional: Setup cell-average homogenization constraints on the simulation – only the new Lagrangian kernels

Constructed MooseObjects

The Tensor Mechanics Master Action is used to construct the kernels, displacement variables, and strain materials in a consistent manner as required for a continuum mechanics simulation simulation. Optionally it generates aux variables and auxkernels to aid in the output of tensor components and scalar quantities.

automatic_eigenstrain_names = true, the eigenstrain_names will be populated under restrictive conditions for classes such as CompositeEigenstrain, ComputeReducedOrderEigenstrain, and RankTwoTensorMaterialADConverter. The input components for these classes are not included in the "eigenstrain_names" passed to the TensorMechanicsAction. Set the automatic_eigenstrain_names = false and populate this list manually if these components need to be included.

Subblocks

The subblocks of the Master action are what triggers MOOSE objects to be built. If none of the mechanics is subdomain restricted a single subblock can be used

    strain = FINITE
    add_variables = true
  [../]
[../]
(../moose/modules/tensor_mechanics/test/tests/finite_strain_elastic/finite_strain_elastic_new_test.i)

if different mechanics models are needed, multiple subblocks with subdomain restrictions can be used.

  [Modules/TensorMechanics/Master]
    [Modules/TensorMechanics/Master]
      # parameters that apply to all subblocks are specified at this level. They
      # can be overwritten in the subblocks.
      add_variables = true
      strain = FINITE

        block = 1

        block = 2
        # the `additional_generate_output` parameter is also only valid inside a
        # subblock. Values specified here are appended to the `generate_output`
        # parameter values.
