     Foam::maxDeltaxyz
 
 Description
-    maxDeltaxyz takes the maximum of the three dimensions per cell:
-    max(hx, hy, hz). Valid for structures hexahedral cells only.
-
+    Delta calculated by taking the maximum distance between the cell centre
+    and any face centre.  For a regular hex cell, the computed delta will
+    equate to half of the cell width; accordingly, the deltaCoeff model
+    coefficient should be set to 2 for this case.
