Hi, I am studying cyclicAMI patches in OpenFOAM, and I have doubts about the matchTolerance and transform properties. I'm posting at the bottom an example from tutorials/.../rotatingFanInRoom.


1- does cyclicAMI use matchTolerance?. I got the impression that only vanilla cyclic uses cell matching.
2- How does the transform option work?. Specifically, rotation vs noordering. Doxygen says transform defines mapping, which sounds like, how field values "jump" from one neighbor boundary to the other during the simulation. However, for transform noordering, it says "leaves the operation (mapping) to the patch", and I don't understand that
3- Can you recommend me best practices and sources to study openfoam dictionaries?. So far I mix: cfdsupport.com, doxygen, find
$FOAM_TUTORIALS -name yadayada, this forum, youtube, and joel guerrero's stuff, but I often find myself missing in depth info. ( I do not know how to code in C)
