Multigrid and Turbulence

Hallo,
I implemented a nonlinear Multigrid in my FV block-structured Code with SIMPLE as Smoother. It speeds up the convergence rate amazingly for laminar flow. However, for the turbulent transport equations (k and eps ; segregated approach in the solver) it does not work. I am not quite sure what to to with the boundary conditions (Wall function; low-Reynolds) and with the sources on the higher grid levels. Can someone give me a hint or recommand some good literature? I am sure that I am not the first one who has have these problems in the past. Thank you very much in advance ! Romuald |
