manny9808 is on a distinguished road
I've been trying to perform meshing of a combustion chamber in ICEM for final year project.The idea is to capture both wall thickness as well as fluid domain inside.Here is the step that I underwent:
1. Created a CATIA model
2. Imported to ICEM, created block, split block for wall thickness and fluid domain region.
3. Associated the block accordingly and created grid.

But the problem is that in order to capture fluid domain as well, I have to create solid element for the fluid region as well like concentric cylinders where outer solid one is the wall and the inner solid one is the fluid.
This approach fails when the complexity of the combustion chamber's geometry increases.

Is it possible to capture the wall thickness as fluid domain together by "creating body" between surfaces for each of them and splitting blocks? Does anyone have better approach? Please help!
