Hi, Peter,

I have finished the mesh, thanks for your help, but I have some misunderstanding about the creation of an inlet/outlet, sorry :-(.

If I have understood, you select the circular edge, pull it, and you have to create another circular surface in filling the surface? What is create a circle that I can mesh and describe in fluent as the entrance of my velocity/pressure flow? Isn't it? 

If yes, I have a weird problem during the meshing. Without the inlet/outlet parts, my mesh is a count of 490 000 cells. But when I add an inlet and an outlet it became 380 000 cells... It's illogical because I add more parts.

Kind regards, Alex
