Dear all,

I am meshing a combustion chamber of a stirling engine mchp with ICEM and I am not sure about heat transfer through walls.

So, I am meshing the fluid domain and the thin solid walls of my geometry with the TGrid tetra volume fill and ICEM does the meshing but although I assign different names for my solid volumes it puts all volume mesh under a single zone named, say, fluid.

Fluent does the spliting to coupled walls allright but I need to ask:

The fluid region and the solid regions are under the same zone name "int_fluid''

The fluid region is a mixture and the solid walls are steel.

if i specify steel material in the BOCOs for the coupled walls containing the solid mesh will the mesh within be treated as steel or will it be treated as int_fluid = mixture?


Thank you very much

All the best
