Default UPrime2Mean and AMI: interpolation error

DanielePeri is on a distinguished road
I am solving the flow around a propeller, using AMI.

Looking at the UPrime2Mean field, solution appears to be completely wrong regarding this quantity, as if the rotating grid and fixed grid do not exchange information correctly.

To be sure that it is not my fault, maybe because of an error in the configuration of the various blocks, I repeated the test on one of the examples of the tutorial, and the situation is shown in the figure. The example is tutorials/incompressible/pimpleFoam/RAS/propeller, whereI only added in /system/controlDict

fieldAverage1
{
type fieldAverage;
libs (fieldFunctionObjects);
writeControl writeTime;

fields
(
U
{
mean on;
prime2Mean on;
base time;
}

p
{
mean on;
prime2Mean on;
base time;
}
);
}


It is a known bug or there is something to take care of?

Thanks

Daniele
