Hi I'm modelling flow through pipes in 3D. I want to mesh (Gambit 2.0) 2 intersecting pipes that have different geometry. One is simple cylidrical pipe, the other with complex geometry. At the intersection between the two pipes I want to model the walls (actually flanges in practise) on both the pipes where the fluid will hit these walls.

Problem is, I import the complex pipe (IGES from Pro Engineer- everything comes out as virtual) and draw the cylidrical one. I draw faces to represent the flange walls and mesh these separately to the solids. The mesh on the solids (including the sorrounding wall)is exported fine into Fluent 6.1 but the flange wall is not. Is it because it's a face mesh?

If so, how to overcome this problem? Because the complex pipe is virtual I don't have many options either. Thanks.

Hi, You could try STEP output from Pro-E which works much better than IGES when importing into Gambit. Gambit will most probably not switch to vitual geometry. Regards emre

thanks! I tried STEP and it's fine now
