+    Foam::regionSizeDistribution
+
+Description
+    Looks up a field, interpolates it to the faces and determines a connected
+    region from a patch where the field is above a certain value.
+    - Writes a field containing all regions starting at given patch
+      ('liquid core')
+    - All other regions are summed for volume and a histogram is calculated.
