saisanthoshm88 is on a distinguished road
I'm totally new to FLUENT. I had a very newbie question in specifying the pressure values to the fan characteristic curve [using the Lumped parameter model].

From the user manual of FLUENT I found that - "
All pressures that are specified and all pressures computed or reported by FLUENT are gauge pressures" and also that Absolute pressure = Operating pressure + gauge pressure.

So could some one please tell me whether the pressure values that are specified for the characteristic curves of the fan are gauge pressures (or) absolute pressures
Best regards,
