+
+Description
+    Processor agglomeration of GAMGAgglomerations. Needs nAgglomeratingCells
+    which is when to start agglomerating processors. Processors get agglomerated
+    by constructing a single cell mesh for each processor with each
+    processor interface a face. This then gets agglomerated using
+    the pairGAMGAgglomeration algorithm with the number of faces
+    on the original processor interface as face weight.

+
+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
