How to properly choose ‘Define By’ option while entering Pressure?

      As far as I learnt, the absolute pressure can never be negative, and the pressure always acts normal (out of) the surfaces of bodies in reality. However, when I try to enter the value of pressure in Structural modules in ANSYS, I see three choices under the 'Define By' option, which goes by Vector, Components and Normal to.

      So I just want to learn that how can I choose the correct option for Pressure. When choosing Vector or components, will the pressure always remain in the same direction as the direction which has been initially inputted. If yes, then what does the Normal to option means?
