Hello,

Select High Order Term Relaxation in Methods. Reduce the Courant number to 2.75 for initial iterations. Reduce the URFs to 0.5 (k and omega). Disable the Compressibility effects in k-w SST and try running. Also, let me know the net mass flow rate, net heat transfer rate and apply a variable report definition to judge the convergence. Use Green-Gauss node based gradient.
