AMI matchTolerance
 
Hello,

i'm getting errors for an AMI fan simulation. At a given timestep, the weights of the AMI reaches 0. I saw that some guys here already faced this problem, but I couldn't find any clear suggestion to avoid it.

To start to investigate this problem I try to understand the matchTolerance value in polymesh/boundary file. Can you explain me it's function? It's a geometrical tolerance for the two sides of the AMIs? In the case described above, should I increase or decrease it?
