Hello!
I'm trying to simulate over an airfoil with flap. I have made a structured mesh over the airfoil but the face mapping fails in the slot gap alone. Using standard initialization I got divergence in the AMG Solver. Hence i then did the hybrid initialization I got a converged solution with no cells with limited turbulent viscosity nor divergence
I have a few question-
1. I had just two/three highly skewed cells, would that be a prob? If yes, is there a way i can get rid of these three cells?
2. Can i rely on the solution i got using hybrid initialization? I'll be doing a grid independence test too but in general can i rely on hybrid initialization? as i read somewhere that the solution changes with different initialization used (standard, hybrid,fmg)

Thanks for your patient replies!
