Class
    Foam::jumpCyclicAMIFvPatchField

Group
    grpCoupledBoundaryConditions

Description
    This boundary condition provides a base class that enforces a cyclic
    condition with a specified 'jump' (or offset) between a pair of boundaries,
    whereby communication between the patches is performed using an arbitrary
    mesh interface (AMI) interpolation.
