 Description
     Linear interpolates volFields to surfaceFields
 
-    Note: gets executed every time step. Could move it to write() but then
-    you'd have problems if you have different write frequencies for different
-    function objects.
+    - at write it writes the fields
+    - it executes every time step
+
+    so it can either be used to calculate and write the interpolate or
+    (since the interpolates are registered) use some other functionObject
+    to work on them.
