Hi everyone,

I am another student novice in ICEM meshing. I am trying to mesh the geometry defined in the picture below. Everything went well for generating the mesh excepted that :

- I defined the surfaces withe "Simple Surface Method From 2-4 Curves" and ICEM created additional lines to split the geometry in three different parts.

- Once in Fluent those lines were named wall_fluid by the software and assigned as "wall". I changed the boundary type to "interface but impossible to set it as an interface (please see second figure below).

Could anyone please help me, its quite urgent. Sorry for the terrible english.
