hi, I habe a problem about the interface in cfx,the error messages as follow:
no control
surfaces have been found at all for Domain Interface 2- |
| . To work around this please set the expert parameter "ggi permit |
| no intersection = t" .

Hope someone can solve the problem.

The error message says exactly what the problem is. Your interface has no connection so is not an interface. If you are doing a transient simulation and the intention is to open an close an oriface then this is fine and use the expert parameter discussed. If this is not intentional then you will have to inspect your geometry and make the two parts of your interface line up.
