Q. A DM model is made up of one part consisting of multiple solid from revolved sketches. User generates an ANF file and reads this into ANSYS.
Why are the nodes in resulting ANSYS mesh not all coincident at the interfacing areas as expected.

A. This is a limitation -- topology in multi-body parts is not shared when the model is exported to ANF, IGES, or Parasolid. This will be more clearly documented at 9.0 with the following statement.

"Note that bodies that are grouped in multi-body parts do not share topology when exported to Parasolid, ANSYS Neutral File, or IGES format. In those cases, all bodies are treated as if they are single body parts."

A possible workaround is to execute "VPTN,ALL" after reading the geometry into ANSYS .
