Convergence criteria
 

Dear all:
I´m 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 wouldn´t matter if it weren´t 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? :confused::confused:

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

Thx in advance...

Uuups i´ll take this thread to the FLUENT specific forum.

Sorry!!
