Points on cyclicAMI patch "sticking" to rotating neighbor patch
 
1 Attachment(s)
I have a case similar to the propeller tutorial, where I have one stationary and one rotating cyclicAMI patch. However, after a bit of rotation, the weights go all out of whack and the simulation crashes. Upon inspection, I noticed the stationary patch seems to have some points that are "sticking" or getting dragged along with the rotating patch. Would this be caused by too low matchTolerance in the createPatchDict?

Think I have solved this problem by setting multiRegionFeatureSnap to true in the snappyHexMeshDict.
