Legacy Kernel-Only Tensor Mechanics Action
Set up stress divergence kernels with coordinate system aware logic
This legacy action will soon be deprecated in favor of the more inclusive TensorMechanics/MasterAction. See the description, example use, and parameters on the TensorMechanics/Master action system page.
Description
The LegacyTensorMechanicsAction is a convenience object that simplifies part of the tensor mechanics system setup. It adds StressDivergence Kernels (for the current coordinate system).
Constructed MooseObjects
The Legacy Tensor Mechanics Action is used to construct the kernels for the specified coordinate system.
Table 1: Correspondence Among Action Functionality and MooseObjects for the Tensor Mechanics Master Action
| Functionality | Replaced Classes | Associated Parameters | 
|---|---|---|
| Calculate stress divergence equilibrium for the given coordinate system | StressDivergenceTensors or StressDivergenceRZTensors or StressDivergenceRSphericalTensors | displacements: a string of the displacement field variables | 
Note that there are many variations for the calculation of the stress divergence. Review the theoretical introduction for the Stress Divergence. Pay particular attention to the setting of the use_displaced_mesh parameter discussion; this parameter depends on the strain formulation used in the simulation.
We recommend that users employ the TensorMechanics/MasterAction whenever possible to ensure consistency between the test function gradients and the strain formulation selected.
