centrifugal compressor stimulation
I'm new to CFX software. I am trying to stimulate a centrifugal compressor. the model include a impeller passage, a diffuser passage,a whole volute. The inlet boundry is total pressure, total temperature, direction of velocity. The outlet boundry is mass flow. it is a steady stimulation. But during solving, the mass flow of inlet isn't equal to outlet,and when I change the mass flow of outlet, the mass flow of inlet isn't changed. I don't know why,and who can help me?
