there is a segregator with bulb and stators.how to set the boundary conditions. i set vecolity and static temperature at inlet,static pressure at outlet.however,after 2000 steps,global residual is about -0.5,massflow error between inlet and outlet is 10%. grid quality:min orthogonality is 9.46,max aspect ratio is 10000(because of bulb). thank you very much!

u can set total pressure at inlet and total temperature ,static temperature at outlet.
