I'm trying to simulate a nozzle in Fluent using a 2D tetra mesh in ICEM. When reading the mesh I receive the following errors:

Warning: Invalid cell type 3. Skipping.
38820 2D interior faces, zone 4.
39 2D velocity-inlet faces, zone 5.
(continues for all zones)

I've tried this 5 times now slightly changing my meshing method and geometry but I get this error every time. Does anyone know what "invalid cell type" or "unreferenced faces" means?
