Hi

I got the following error when I tried to run my simulation in CFX, which consists of several parts joined together by interface. Can anyone advise on how to solve this error? Thank you in advance.

+--------------------------------------------------------------------+
| ********* WARNING ********* |
| First side of interface |
| Impeller Cone to Inlet Passage wo IGV |
| seems to contain a vertex at R=0 (Rmin/Rrange < GGI ETA TOLERANCE).|
| This is not supported for stage interfaces. |
+--------------------------------------------------------------------+

The first 3 error message are self-explanatory, aren't they? The last error is probably caused by the first 3.

Thanks for the response. I think I found the source of error. One of my domain has zero radius and CFX does not allow the use of automatic pitch change in the setup of interface.
When I specified the pitch angles explicitly, the problem is solved.
