I set the inlet as totalPressure zero; and outlet with a constant outflow velocity (entrainment), so the flow field is smaller than zero generally. Now when I tried to obtain total pressure using Code: postProcess -func "totalPressureIncompressible(p,U)" The obtained total pressure is even smaller than static pressure. I really wonder how that happens. Best Regards,
