creating separate bodies
 

I want to create 3 separate bodies (insulator-adsorber layer_fluid). I have done it drawing the three bodies and freezing them after that i created them. In the mesh part it sees three separated bodies but when i open fluent it only sees one body (in the cell zone conditions i only see 1 body).
Does anyone know what the problem could be/how to solve it?
Thanks!

do some tutorials

Thank you for the reply, the problem is that most tutorial with complex geometries are provided with the mesh already constructed...that's why had that problem
