Inlet pressure boundary condition

  My design requirement is inlet pressure of 5 bar, so I am modelling a laminar flow with pressure based solver . I am confused about what inlet pressure to specify. The defualt operating pressure in ansys fluent is 1 bar (101325), do I specify the inlet pressure in the dialoage box as 4 bar or 5 bar? I am confused what do you specify in ansys- total pressure and gauge pressure?

  Fluent uses gauge pressure, so 4 bar would be appropriate for your case.
