Negative total pressure

Hi guys,

i am running a HVAC duct (incompressible flow) analysis. the geometry has totally eight outlets. the problem is, at some of the outlets (at last) i am getting total pressure values in negative. what does the negative sign indicate?

please help me....

Thanks in advance

The total pressure value reported by Fluent is the gauge pressure with respect to the operating pressure defined in the Operating Conditions panel.
