INSAction
This class allows us to have a section of the input file for setting up incompressible Navier-Stokes equations.
Overview
This action is used for setting up incompressible Navier-Stokes equation over a subdomain. Boundary conditions must cover the entire boundaries that enclose the subdomain. This action is triggered with Modules/IncompressibleNavierStokes input syntax.
