Class
    Foam::processorCyclicFvPatchField

Group
    grpCoupledBoundaryConditions

Description
    This boundary condition enables processor communication across cyclic
    patches.

    \heading Patch usage

    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            processor;
    }
    \endverbatim
