Class
    Foam::cyclicACMIPolyPatch
 
Description
    Cyclic patch for Arbitrarily Coupled Mesh Interface (ACMI).
 
    Mixes cyclicAMI behaviour with non-coupled patch behaviour using
    the overlap area fraction. The non-coupled patch is specified through
    the nonOverlapPatch keyword.
 
Usage
    Example of the patch specification:
 
        type            cyclicACMI;
        neighbourPatch  ACMI2_couple;       // cyclicAMI neighbour patch
        nonOverlapPatch ACMI1_blockage;     // patch for uncoupled faces
 
        // Optional time-dependent scaling (PatchFunction1)
        scale           table
        (
            (0.00   1.0)
            (0.02   1.0)
            (0.0201 0.0)
        );
