Hello everybody,

I try to run a naca profile in 2D. I studied it in the air with no problem, now I try to study it in the water and since 10 degrees of incidence I have stability problems.
I use same Re, turbulence intensity, turbulence length scale.
I change U, nu, rho from air values to water values.

Can someone give me an idea to stabilize it? I tried to increase nNonOrthogonalCorrectors and decrease relaxationFactors but not very successfully ...
