I have been simulated as follows.

inlet massflow : 168,000 kg/s

outlet pressure : rho*g*h

i check massflow outlet, only 155,000 kg/s

what problem??

FAQ: http://www.cfd-online.com/Wiki/Ansys...gence_criteria

Your simulation is not adequately converged, so the results are rubbish. That is why the inlet flow does not equal the outlet flow. Read the FAQ for tips on how to get this to converge better.
