Hi all,

I have done some tests with simpleFoam and got it running quite smooth with 1st order upwind div-Scheme. However residuals converge very slow (Turbulence has to be under-relaxed with 0.1).
Nevertheless, I failed to run it in second order even as a restart of the first order result. Turbulence values are always exploding. I tried linear upwind, linear and limited linear 1. What are recommended 2nd order div-Schemes?
