good morning everybody

at the present time. i am simulating the 3D centrifugal compressor. and i am still confuse to setting the boundary condition. so at the present i have the initial condition at the inlet is pressure and temperature. so i have to setting with pressure inlet. and if i setting in outlet with outflow. fluent give some caution that pressure inlet and outflow is not compatible. and then i set the outlet with pressure outlet. but i dont know what must i fill in gauge pressure in pressure outlet because my purpose is to get pressure outlet and mass flow rate in outlet. so i hope u can help me give me suggestion to solve this problem. and now i am still using MRF method. in further my simulation i will use the sliding mesh. but i dont know to setting this method.

please help me..

thanks..
