Mass Flow Imbalance

Ed Mueller

I am runing a CFX analysis on a fluid pump, and when I look at the results, everything seems to be in order.

However, when I compare massflow at inlet to massflow at outlet, the outlet massflow is exactly one-half that of the inlet (the inlet massflow is correct according to hand calcs).

When I check the massflow out of the impeller, it is the same as that at the inlet so something is happening in my fluid out domain where the massflow out of the fluid out domain is precisely half of the massflow into the fluid out domain.

Does anyone have any ideas on why this is? Does this mean my run is not converged? I found it odd that it is exactly half of my inlet mass flow (to about .00001 decimal places).
