AddAuxVariableAction

Add auxiliary variable to the simulation.

This action derives from the AddVariableAction. It checks the auxiliary variable family and type before adding it to the Problem.

Auxiliary variables, which are not directly being solved for in the nonlinear system, are specified as an object inside the [AuxVariables] block.

More information about auxiliary variables can be found on the AuxVariables syntax page.
