Hello. I'm runnig a file with laminar and turbulent (K-w,SST). The turbulent model converge quite fast, but the laminar model (same mesh, same conditions...) is stabilize to around 5.10^3 to continuity and don't decrease more. How can be possible that the turbulent model converge to 10^5 adn the laminar don't?? Thanks

either your model is turbulent, or it is laminar. But not both at the same time (except special laminar zone you enforced).

I Know, but It just in the transitional Re. So I tried to simulate both of them to check them. Is that a problem to converge??

I would say that if the laminar model doesn't converge, it seems that your model is full turbulent, and you are not in laminar-turbulent transition (I suppose). What is your Re? and what kind of calculation are you trying to simulate?
