Autodesk CFD Duct pressure loss

Hi

We have some duct pressure tests in CFD, and run into a question.
Autodesk CFD gives two results in the report.

Press: max/min
Ptotl: Max / min

witch one is the correct value for the static pressure in the system ?

when calculatet in other software the (Press: Max) is the closest to the results done by other software.

Best Regards
Kasper

Just use Static Pressure.
In fact, it might be better to use cut planes and the bulk calculator rather than the report as those values could be anywhere...
