need help in meshing of volume inside volume

Hi,

I am relatively new to CFD . I am trying to mesh a no-frost refrigerator. After making the geometry of the entire refrigerator in DM, without the shelves, I have drawn out fluid domain. Now when I mesh and go for named selection for boundary condition I can not get access to the inlet outlet ducts for air flow to the refrigerator section from the freezer section. My entire geometry is just one part. This is because my ducts are inside the two sections of refrigerator. I would appreciate any help in this matter.

supress the outer body and then dry...

just a suggestion from amateur

Thanks Maaz for your quick reply.

As I said I have the entire geometry as one part. If I don't have it as one part then I can not get fluid domain drawn from the geometry, or if I have separate bodies then fluid domain will be in two or more body. In that case the boundary conditions will become a problem. I have used fill (cavity) to get the fluid domain.
Any other suggestions?
