Class
    Foam::cyclicFvPatchField
 
Group
    grpCoupledBoundaryConditions
 
Description
    This boundary condition enforces a cyclic condition between a pair of
    boundaries.
 
    \heading Patch usage
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            cyclic;
    }
    \endverbatim
 
Note
    The patches must be topologically similar, i.e. if the owner patch is
    transformed to the neighbour patch, the patches should be identical (or
    very similar).
