GGI mismatch patches
 
I'm using cfx to simulate the performance of an industrial axial fan
The two patches matched by the GGI have common shroud but different hub radius.
The picture below shows the velocities contours on the bigger side of the interface

It is possible to see a band of zero speed close to the shroud but
it is supposed to be in the hub zone.
How is it possible to sort this misalignmet?
I couldn't manage to work out this.

Thaks in advance for your help.
