Hi, i'm very new to this program. I am doing the centrifugal pump analysis, i'm learning form youtube and research papers. There are a lot of problems:

1. the velocity vector seems incorrect, i set the impeller fluid and the impeller wall to rotate. However, the velocity vector seems like not moving outward as i should. I rotating in circular manners.
2. The interface between the impeller and volute, the results seems like it does not interface very well. I did not share the topology instead i use the interface. 
3. the pathline is very confusing
