CNSAction
This class allows us to have a section of the input file like the following which automatically adds Kernels and AuxKernels for all the required nonlinear and auxiliary variables.
Overview
This action is used for setting up Navier-Stokes equation over a subdomain. Boundary conditions must cover the entire boundaries that enclose the subdomain. This action is triggered with Modules/CompressibleNavierStokes input syntax.
