First, as I have mentioned at the begining "I change the surface integrals to Area-Weighted Average or Facet Average, the problem is still exist." and "When I export the ASCII files of total pressure, dynamic pressure and static pressure, the total pressure is not equal to the sum of the static pressure and dynamic pressure at the outlet. So I think this problem is not caused by the types of surface integrals."

Second, according to your advice I set the residual to 1e-7 run on the calculation and there is a problem. The calculation converge only to 1e-4 (Show in Figure 8). Does this the main reason of the problem? What should I do to improve it?Â
