Total pressure obtained by postProcess utility is smaller than static pressure
 

Hi foamers,

I am doing a calculation in an internal flow with complicated geometry. 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

The obtained total pressure is even smaller than static pressure. I really wonder how that happens.

Best Regards,
