Hmm, I have created a new variable custom-function-0 equal to the sum of static + dynamic pressure. When I report it using surface integrals the problems are still exist (Show in Figure 9). Custom-function-0 is not equal to total pressure in surface integrals, why?

Until now, my problems have not been solved and I think you may have forgotten my original questions. So I think it is necessary to emphasise that my questions are why total pressure of the outlet is higher than the inlet? Why total pressure is not equal to the sum of static pressure and dynamic pressure when I use pressure outlet boundary condition at the outlet?
