Hello, everyone.
In the CFX mixing plane interface, you set up two sides of the interface. After running a simulation, I've observed that these faces do not show the same values—for example, the velocity on one side differs from that on the other. I would like to understand why this happens.
My second question relates to the CFX Solver Modeling Guide, which states regarding the mixing plane (Stage) model:
"the Stage model performs a circumferential averaging of the fluxes through bands on the interface."
Based on this, I expected each circumferential band to have a constant value. However, after simulation, this does not appear to be the case—contour plots of the interface still show gradients in both the circumferential and radial directions

Did you read the sentences carefully? in particular,

"the Stage model performs a circumferential averaging of the fluxes through bands on the interface."

which value should be uniform? (constant is about time not space)

I've found the problem it is said that fluxes are conserved and averaged circumferentially not the points data like velocities. But I didn't understand

constant is about time not space

I'm also a little confused about how two sides of the mixing plane interface have different profiles
