 Description
     IDDESDelta used by the IDDES (improved low Re Spalart-Allmaras DES model)
-    The min and max delta are calculated using the double distance of the min or
-    max from the face centre to the cell centre.
+    The min and max delta are calculated using the face to face distance of
+    the cell.
