Hello,

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 after 800 iterations, the inlet appears 100% reflow(回流),and it con't convergenced, who can help me? thanks!
