Hi,
What kind of simulation are you doing? In any case does not make sense define something outside the domain of solution. The solver knows onky the quantities defined in each cell or at the boundaries... Thus if you define something badly, I suspect that fluent makes the decision for you somewhere in a default position.
Total pressure is p+0.5*rho*U^2, while absolute pressure is the pressure added by some reference pressure (e.g. Atmospheric). The total pressure is thus a measure of the energy of the fluid in a point (please remember bernoulli eqution). For incompressible flows, absolute pressure is not import, only the pressure gradient matters.
