HI,there!
I got a case which is to calculate the back pressure of an exhaust system, and it's perfectly converged ,but i was a little bit confused when it comes to post processing as the followings: In the surface integrals of the report: area-weighted average total pressure Pa inlet 52716.32 outlet 1773.2864 net 24235.805 problem is the net doesn't equal inlet minus outlet.why?

Because "net" means the area-weighted average of both faces and not its difference.
