hi friends,
i'm working on a geometry in ICEM for Cfx Pre flow simulation,
the calculation domain is fluid , it has a rectangular form and extruded for 3°.
inside the domain the duct of the flow,
so i'm struggling with this duct to consider it in the domain as a wall part , i have tried some tips but it doesn't work , the part does not appear in cfx pre
i hope that someone can help to fix this problem

greetings

Your text is very unclear. I need to read it 5 times to understand it. And without pictuures of your geometry it is even more difficult to understand. Please be more precise next time.

But it looks like you work in ICEM and have a fluid volume with a duct as an obstacle and this duct does not appear in Pre. Does this duct have any volume or is it a sheet (thin surface)? Please show a picture of your geometry.........

hii ,sorry but , i tried to simplify my explanation
the duct is a sheet (a thin surface)
i have attached a picture of the geometry
i hope that every thing is clear

thank you for your help

Provided you make a tet/prism-mesh, you should go to Mesh > Part Mesh Setup.
There, on the right hand side, you should tell ICEM that your Geometrical Surface is an Internal wall, or a Split wall.
The difference is that the Internal wall will have the same mesh on both sides of the internal wall (conformal), the split mesh will result in different mesh.
As a consequence, the Internal wall will give you the option in Pre to define it as a wall or as an interface, i.e. no wall. The split wall can only be used as wall. It has therefore less flexibility, so I would recommend internal wall.
