Total pressure to static pressure ratio
 
Hi all. I have the following problem: flowbox of an engine manifold, Inlet BC stagnation, outlet BC pressure.Turbulent (ke) compressible flow. The reference pressure is 98000Pa, and the reference cell is on the pressure boundary. The total pressure is 2000Pa (relative). The calculations seems to run properly till convergence, but the output values of pressure are strange, and I have the warning message "ratio of total to static pressure (at stagnation boundary)less than 1..." The total pressure at inlet is 101432,static pressure at inlet is 101233. How can it be possible?

Have you check the ratio of every cell in the inlet?
