Hello, 

 

Fluent always uses the gauge pressure. However, if you set the Operating Pressure to zero, your gauge pressure becomes the same as the absolute pressure, which can be determined using reports. Caution needs to be taken while setting operating pressure to zero. Check this for more information: ANSYS FLUENT 12.0 User's Guide - 8.14.3 Setting the Operating Pressure (enea.it)

 

Thanks,

Nikhil
