Hello Gmsher,

I hope that you all well. I am doing a validation study on a shrouded diffuser at 6 m/s. I have developed the domain and the shrouded diffuser geometry. Moreover, I have made sub-regions to make it easy to mesh. So far, I have done 80% of the problem, but I am still facing a problem to obtain a converged solution. I have run the case as a laminar and turbulent, I have not got a converged solution yet. My guess is properly because of the discontinuity of the sub-regions or it might be something not in my knowledge. I am asking if someone could guide me to obtain the converged solution (See the picture below). I am attaching a picture shows the strategy that I have used and hoping some guidance.

Thank in advance,
