Help on judging imbalance plots

Hello,

I could use some help on judging the imbalance plot in CFX solver module. Unfortunately I could not find much information about this in the help texts. The P-Mass Imbalance in this plot is jumping randomly from -100 to 100, where as the other imbalances seem to stay at zero. I'm wondering how to inteterpret this and if it has got something to with the other residuals. The boundary is a sphere, set to opening, entrainment, static pressure option.

Thank you very much for your help.

Stefan
