+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.
+
+    \heading Patch usage
+
+    Example of the boundary condition specification:
+    \verbatim
+    myPatch
+    {
+        type            cyclicACMI;
+    }
+    \endverbatim

+oscillatingInletACMI2D
+
+This tutorial case gives an example of the Arbitrarily Coupled Mesh Interface
+(ACMI) usage.  The mesh is composed of two mesh regions: an inlet channel which
+oscillates in the +/- Y-direction, and a fixed mesh region.
+
+Each ACMI patch requires the specification of a 'non-overlapping' patch.  In
+this example, the non-overlapping patches are described as walls, e.g. taken
+from the constant/polyMesh/boundary file:
+
+    1. First ACMI poatch pair applied to the inlet channel outlet
+
+        ACMI1_blockage
+        {
+            type            wall;
+            nFaces          40;
+            startFace       43680;
+        }
+        ACMI1_couple
+        {
+            type            cyclicACMI;
+            nFaces          40;
+            startFace       43720;
+            matchTolerance  0.0001;
+            transform       noOrdering;
+            neighbourPatch  ACMI2_couple;
+            nonOverlapPatch ACMI1_blockage;
+        }
+
+
+    1. Second ACMI poatch pair applied to the fixed mesh region inlet
+
+        ACMI2_blockage
+        {
+            type            wall;
+            nFaces          96;
+            startFace       43760;
+        }
+        ACMI2_couple
+        {
+            type            cyclicACMI;
+            nFaces          96;
+            startFace       43856;
+            matchTolerance  0.0001;
+            transform       noOrdering;
+            neighbourPatch  ACMI1_couple;
+            nonOverlapPatch ACMI2_blockage;
+        }
+
+
+In the above, the ACMI1_blockage and ACMI1_couple patches occupy the same space,
+with duplicate points, edges and faces.  The ACMI2_blockage and ACMI2_couple
+patches are created similarly.
+
+The duplicate patches are initially created using the createBaffles utility.
+Firstly, the original (non-duplicated) patch faces are collected into zones
+using the topoSet utility.
+
+Each ACMI/no-overlapping patch pair is specified using a master-slave approach.
+However, since we are generating boundary patches (which are always master
+patches) the slave patches are simply defined using 'dummy' entries, e.g.:
+
+    type        faceZone;
+    zoneName    couple1Faces;
+
+    patches
+    {
+        // create blockage patch
+        master
+        {
+            //- Master side patch
+            name            ACMI1_blockage;
+            type            wall;
+        }
+        slave1 // dummy entries only
+        {
+            //- Slave side patch
+            name            ACMI1_blockage;
+            type            wall;
+        }
+
+        // create cyclic ACMI patch
+        master2
+        {
+            //- Master side patch
+            name            ACMI1_couple;
+            type            cyclicACMI;
+            matchTolerance  0.0001;
+            neighbourPatch  ACMI2_couple;
+            nonOverlapPatch ACMI1_blockage;
+            transform       noOrdering;
+        }
+        slave2 // dummy entries only
+        {
+            //- Slave side patch
+            name            ACMI1_couple;
+            type            patch;
+        }
+    }
+
+Boundary conditions must then be applied to all geometric patches in the usual,
+manner, and the cases can be executed in parallel (as shown when running the
+Allrun-parallel script) without any speacial treatment, i.e. the case set-up is
+the same as when operating in serial mode.

+//   a set of patches or as a faceSet)
+// - always: order faces on coupled patches such that they are opposite. This
+//   is done for all coupled faces, not just for any patches created.
+// - optional: synchronise points on coupled patches.
+
+// 1. Create cyclic:
+// - specify where the faces should come from
+// - specify the type of cyclic. If a rotational specify the rotationAxis
+//   and centre to make matching easier
+// - always create both halves in one invocation with correct 'neighbourPatch'
+//   setting.
+// - optionally pointSync true to guarantee points to line up.
+
+// 2. Correct incorrect cyclic:
+// This will usually fail upon loading:
+//  "face 0 area does not match neighbour 2 by 0.0100005%"
+//  " -- possible face ordering problem."
+// - in polyMesh/boundary file:
+//      - loosen matchTolerance of all cyclics to get case to load
+//      - or change patch type from 'cyclic' to 'patch'
+//        and regenerate cyclic as above
