Hi,

i want to simulate a 2D hydrofoil section, but simpleFoam do not converge (it stops after 10-50 steps) . I run the same case with the SA turbulence model and everything works just fine. But my Cd values are a bit too high so I want to try the KOmegaSST model.

It is a NACA4412 Section @0°.
U=4.75m/s
L=0.23m

Maybe you can take a look over my BCs, i think here is my Problem.
