Dear all:
IŽm modelling a WORTMANN profile and studying its behaviour (Re=3x10^5). K-w (SST) model seems to reach convergence quick, but when switching to Reynolds Stress turbulence modelling, convergence tends to take far more time. That wouldnŽt matter if it werenŽt because i can never get a single value, just a range of them, and i can only take a semivalue...Is that correct? Any ideas to reach convergence?

(By the way, i have to study later the same model with k-kl-w turbulence modelling and iŽve run a few cases... OMG convergence seems impossible there!!!! )

Thx in advance...
