Hi,

I'm working on a multistage pump which has rotary and stationary domains.

I set a (frozen rotor) interface between a rotary and stationary where it can calculate the pressure by massflowAve(Total pressure in Stn frame)@ side 1 and massflowAve(Total pressure in Stn frame)@ side 2.

The problem is that the pressures on both sides aren't equal and their difference is more than 30%.

Thank you for your help.
