Class
    Foam::cyclicACMIFvPatchField

Description
    This boundary condition enforces a cyclic condition between a pair of
    boundaries, whereby communication between the patches is performed using
    an arbitrarily coupled mesh interface (ACMI) interpolation.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            cyclicACMI;
    }
    \endverbatim
