Hypermesh CFD: CAD geometry is shallow inside

Hi!
When I import a CAD geometry into HyperMesh CFD, it appears shallow or hollow, even though it is actually a fully filled solid volume. Does someone know why this happen? What do I need to do to solve this?

For materials, I need to add the inside volume (in red) as material 1 and the walls volume (in graw) as material 2. Material 1 is a solid volume and material 2 is shallow.

Thank you!

    At present, the cut plane in HMCFD does not show the filled solid - only the boundaries. If the icon next to the body name in the Part Browser looks like a solid box (which they both do in your image) they are true solids. Otherwise they would be just surface bodies. Once you generate the volume mesh, the cut plane would then show the mesh filled in the solids.
