Multigrid with SIMPLE Navier-Stokes Solver
 
I am trying to adapt a non-linear multigrid scheme to the SIMPLE 2-D incompressible Navier-Stokes solver. I have gotten the nonlinear multigrid to work fine with a simple heat equation on a 2-D plate with generation. I have read multiple papers and a few sections of books describing the multigrid technique, yet I have yet to find one that goes into detail on what exactly to restrict to a coarser grid and how to solve what was restricted. Any help on the subject would be greatly appreciated. Thanks.
