I need your help. At university, we were doing flow simulation of a pump that is used by SolidWorks as validation for the simulation of rotation (SolidWorks Flow Simulation 2013 - Technical Reference). The BC are flowrate at inlet and environmental pressure at outlet. We wanted to calculate its efficiency. We need answer for some questions:
1) Which parameters do we need to choose to calculate pressure drop?
2) Which parameter should we use as a convergence criterion?
3) Why the value of torque do not converge?
Thank you in advance,
