NumbatSFAction

Action to automatically add all variables, kernels, boundary conditions and postprocessors for the dimensionless formulation

Description

The NumbatSFAction adds all of the nonlinear variables, kernels, aux variables, aux kernels and postprocessors typically required in a dimensionless Numbat simulation.
