Flow around a flanged diffuser problem?
 

Hello Foamers,

I am doing a simulation around a flanged diffuser using simpleFoam based on a paper that I found on the internet . The reason of this study is to understand how to use proper boundary conditions and do a quick validation. I have successfully created the mesh using snappyhex mesh as in the attached picture. I know that the mesh might not be highly sophisticated, but it is made to see at least what is going. I have been trying to impose the proper boundary conditions, but it is little bit kind of challenging. I am asking if somebody could help me to get up to the speed and make it happen.

I am attaching the case file of the example and wish any help.
