importin autogrid mesh in cfx
 

hey,

i have an .cgns file with a mesh of an axial fan which was generated with autogrid. now i want to simulate this fan with cfx.
but when i import the mesh in cfx-pre i only get the 3-d volumes of the blocking and the 2-d areas are always the whole surface of the 3-d volume. so like this i cannot define any boundary conditions like inlet outlet and wall conditions.
is there a way to get the connection between the blocking of the mesh automatically?
i hope the description of my problem is not too confusing.
i would be really happy if someone of you can help with this
