Pressure outlet condition is ignored

Hi,

I just found, that for my rotating case (moving reference frame) the intended gauge pressure (-1000Pa) is ignored.
So, when I check the static pressure I get values from -1400Pa up to +1100Pa (for three outlets, where each have a gauge pressure of -1000Pa). But the heat transfer results seem to be reasonable. Also, the mass flow rate at the outlets is almost the same as in the non-rotating case (gauge pressure of -1000Pa is achieved at all outlets)....

Anyone recognized the same?

I guess it's because of "Radial Equilibrium Pressure Distribution" ....

.... but still the first outlet of the different outlets-rows have more or less with the same distance to axis of rotation ....
