Thanks a lot for your help,
I change few settings in my fvSchemes file, it seems to work now with this settings:

divSchemes:

div(phi,U) Gauss upwind grad(U);
div(phi,k) Gauss upwind grad(k);
div(phi,omega) Gauss upwind grad(omega);
div(phi,epsilon) Gauss upwind grad(epsilon);
div((nuEff*dev(T(grad(U))))) Gauss linear;
}

laplacianSchemes
{
default Gauss linear corrected;



I didn't change everythings cause I'm using the OF2.0

I let you know of my advances...

Thanks again
