Class
    Foam::cyclicPeriodicAMIPolyPatch

Description
    Cyclic patch for periodic Arbitrary Mesh Interface (AMI)

    Uses automated matching to fill all of the faces on owner and neighbour.
    Can be used for translational periodic matching as well. Uses the
    transforms from a specified periodic patch to transform the geometry.
