Fluent 13 Interfaces
 

Hi all,
I have a problem with the fluent interfaces. I have a domain made by several parts. Each part is meshed independently, so I have a non conformal mesh. On order to connect the volumes, I have used the fluent interfaces (whitout coupled connections). My model is a gearbox with 2 rotating gears inside and a bi-fase flow. The problem is that there is no flow between the different volumes. In the volume in which there are the rotating gears, the mixture has a velocity, in the other volumes (connected to the first one by interfaces) the mixture has no velocity.

Has someone an idea of what can I have made wrong, or if it is a problem of the software?

Regards
F
