Did you set a reference pressure in the domain? If yes, all pressure values will be relative to that, to get the absolute pressure, use the respective variable provided in CFD Post.

thank you for your reply, it seems that, i have set something like that accidentally. After i saw your reply, i searched a bit in Google, but i couldnt find some useful information about it. they are all related to Fluids simulation or something like that. Im new in this Forums...could you pls tell me again where i can set reference pressure or where i can find "respective variable" in CFD?
