What do you mean by internal boundary ? I'm new to Fluent, and some concepts are difficult to understand. Regarding the mesh resolution, I increased the number of elements in the interior and at the boundary between the meshes. I don't think the two sides are matched; should I enable the option "matching" in the mesh interface parameters ?
The model has turned over half a turn. The water in the buckets on the top of the wheel was just a test to see what happened if I initialized some cells, if the gravity would work, and on those ones, it worked physically. 
For the open channel part, I only created and pressure inlet and initialized some cells with water (on the same water level as the inlet). For the downstream flow, I left it open.Â
