Hi.
I'm meshing a complex geometry of a gas turbine combustor using ICEM. The mesh is composed by both the fluid and the solid parts.

I made the tetra mesh for the entire model (fluid and solid) but when I go to build the prism layers the latter are added also at the solid mesh (see the simplified figure in attach).
I defined the parameters of the prism layer at the surface that is the interface between the solid and fluid region, but I want that the solid wall doesn't contain the prism layers!!!
How can I fix this issue?

thank you in advance for your time and consideration.
Best regards.

kad will become famous soon enoughkad will become famous soon enough
In the menu for selecting prism parts activate the volume part "fluid" as well. Check the ICEM manual for "compute prism mesh".

Hi...and thank you very much for your rep
ly.
So, Have I to check both surface and fluid volume? It seems quite redundant!
All the best.
Roberto

You must put the check mark also to the part name of the volume mesh of the fluid side, and solid side must be unchecked. Marking none of the volumes will result in prisms in all of the volume parts that is adjacent to the marked surface.

Thank you guys for your help.
Unfortunately, the problem is not solved yet.

Firstly, I create a tetra mesh, obtaining different domains (two solid walls and three fluid domains).
Now, I want to create the prism layers at the wall. When I'am going to create the prism layers, have I to click on "Replace" or "Merge"?

If I click on merge other domains overlap the previous ones.

Do you suggest to create simultaneously the tetra and the prism layers?

I have made a quick test and it does not work also in my case... The prisms are generated in both directions.

Could you post your part mesh setup?

Actually now it works! A colleague of mine had created two bodies with the same name for the two solid volumes, but giving different names it has been fixed.
