i'm dowing a small analysis on CFX, i'm getting unlogical results, and while running the solver, i see this message with each Iteration :
total temperature 300K
the outlet condition : relative pressure : 0kPa
any opinion ?

I really should this answer up as a FAQ, it has been asked thousands of times. Do a search of the forum and you will find lots of questions on it. Also the CFX documentation discusses it.
It merely says that you have backflow at an outlet and this is not allowed. To stop it the solver has created artificial walls at the outlet to stop the backflow. Whether this is acceptable or not depends on your problem, but in general it is best avoided. The best fix is usually to move the outlet further downstream to where the flow is fully in one direction.
