Help in meshing using GAMBIT!

[piso]

Hi all,

I am trying to make a mesh file of the geometry shown in the attachment. When I export the mesh file and open it in Fluent, it makes a wall at the face shown in the attachment. How can I make it hollow so that fluid can pass through it

Please help me!

Thank you.

You have to merge the overlapping faces together using "connect faces" option in gambit. Fluent automatically makes a wall boundary condition for faces which are overlapping.
