Default how to avoid AMI weighting 0

Hi foamers,

I am working on a rotating geometry simulation, moderate Re.

I get error after significant number of timesteps where AMI min has gone to 0, I understand that when there is mismatch between level of refinement of the body (A propeller/plate etc) and the rotating domain in which it is present leads to AMI go to 0.

but how do i calculate that thing a-prior i? is there a rule of thumb?

after setting up BC, making sure mesh is proper, it gets frustrating to know that AMI weighting goes to 0 at say iteration number 20000, is there a way to avoid it?
