Surface disapears from ICEM to FLUENT
 

Hello everybody,

I am using ICEM to mesh my geometry before working on it with FLUENT.

In my geometry, there are several plates to guide the fluid (air).
Basically it is a big cylinder with a tangential inlet after which those plates are arranged to distribute my flow.

The problem is, that those plates are not there anymore after I open the finished .uns file in FLUENT. The plates do only have a surface mesh in ICEM, because the thickness is negligible in comparision to my big cylinder.

I already tried to give them the boundary condition "wall" in ICEM, but this does not change anything.

Does anybody know, what I do have to do, that those plates are included in FLUENT?

Thanking you in anticipation for any help!
