Mass flow rate at inlet and outlet are not equal

jiaen961997 · January 9, 2019, 03:16

Hi. I am currently running Fluent on stator of turbine blade. During the simulation, the graphs on pressure and mass flow rate at inlet and outlet are experiencing repeat cosine graph after 6000 iterations. When I stop at simulation at 15000 iterations, I checked that the simulation is having the mass flow rate at outlet is negative and lower than that at inlet. Can anyone suggest to me what can I do to make the mass flow rate equal at inlet and outlet and how to solve the repeated cosine graphs?
