CFD Student Guest Posts: n/a	Dear CFD people, I am implementing Multigrid method into my 2-D finite volume density based inviscid flow solver using central differencing and Roe schemes, Runge-Kutta time stepping, Local time stepping, residual smoothing. Can anyone please let me know how to prolong solution corrections to ghost cells next to computational boundaries? Regards.
