PRESSURE OUTLET

      I am doing CFD of 3d wing to estimate the forces. The cruise height is 6000ft, can anyone tell me that what value should I put in GUAGE PRESSURE (while setting up pressure-outlet boundary condition) 


      AT 6000ft


      absolute barometer= 609 mmHg


      absolute atmospheric pressure= 81.2 KPa


      GUAGE PRESSURE = ???

      I'd use a far field boundary and revise my other settings. Have a look at the NACA air/aero foil examples and tutorials.

      I have searched on google but did not get my answer, as I am a beginner.


      By default, the pressure outlet is set to 0 pressure, does this represents that we're on sea level? what value should I put in gauge pressure if I am at some altitude? the far-field boundary condition also requires a value of gauge pressure.
