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? Regards BastiL
