hi...could someone please help me in deciding the boundary conditions for CFD on a pump....
PROBLEM DESCRIPTION:
1. I have to perform analysis on a fluid in axial flow pump, so i have made the inverse geometry, did the meshing and imported the file in the fluent.
2. I have some mass flow at the inlet, a desired pressure at outlet and the the pump is rotating at a certain speed.

but the problem is that the final results are not showing any pressure developed across the pump..may be i am not able to input the boundary conditions properly (despite inputting the inner wall of my inverse geometry as rotating, i guess the fluid is not rotating)...
Please help me regarding this.....
