I am encountering the following problem when trying to mesh a FSAE car (it has already been simplified). In SC and DM the analysis tool claims that the geometry is error free, thus, I cannot find the problematic area.

Error: After Surface Mesh, the model consists of 7 free nodes that could not be repaired. The CAD needs to be repaired before proceeding.

Error Object: #f

On the other hand, I can properly mesh the geometry in the old mesher (the one that's called literally mesh). I'd like the mesh to be formed with poly-hexcore, so I need to mesh the geometry in Fluent Meshing.

If geometry is error free, please make sure that it forms a closed region. It should be a solid body in SpaceClaim. 

Also please change sizing. Using coarse size may give free faces. 

Also if your geometry is multibody part then please make sure you have used Share option.
