What is the difference between absolute total pressure and absolute pressure in star ccm+?

Absolute pressure is the static pressure (not a gauge pressure, which is what the absolute refers to)

Absolute total pressure is the stagnation pressure, also not a gauge pressure

Hello rwryne,

Thanks for the reply!I found one more field variable which is just "pressure" in star ccm+.Does this denote the gauge pressure?Does it include any other components?I am posing this question because the three pressure variables:"absolute total pressure","absolute pressure" and "pressure"indicated different values in my case.

They should all indicate different pressures, except on walls! There are actually 4 scalar fields related to pressure, you are leaving off Total Pressure. But yes, "pressure" and "total pressure" denote gauge pressures.
