centrifugal compressor boundary condition
 

good morning everyone
right now i am simulating the 3D centrifugal compressor. i use multi reference frame. and i still confusing regarding the boundary condition for my case. actually i only have data for inlet condition and rotating speed. what kinds of boundary condition that should i choose? i would like to simulate use steady simulation and the available data only suction pressure, rotating speed design and fluid temperature in suction zone. please give me some advice if everyone know that. i really need your help.

thanks
best regard
