To be honest, it depends on what your end modeling goal is? Are you attempting to model the flow inside this pump to understand the performance? Then, I'd try to use pressure inlet and mass flow outlet boundary condition. nPlease have a look at the following YouTube video which goes into the details of how to set-up such a problem. Yes, the pump is different and the performance would also be different. However, you should be able to borrow a few modeling elements from here for your simulation. nI hope this helps.nThanks.nKarthikn n
