+
+Description
+    This function object creates a volume field with zero-gradient
+    boundary conditions from another volume field.
+
+    The result can be used, for example, to post-process near-wall
+    field values.
+
+    Example of function object specification:
+    \verbatim
+    zeroGrad
+    {
+        type        zeroGradient;
+        libs        ("libfieldFunctionObjects.so");
+        fields      (U "(T|k|epsilon|omega)");
+        result      @@nearWall;
+        ...
+    }
+    \endverbatim
+
+    \heading Function object usage
+    \table
+        Property | Description                | Required  | Default value
+        type     | type name: zeroGradient    | yes       |
+        fields   | Name of fields to process  | yes       |
+        result   | Name of results            | no        | zeroGradient(@@)
+        log      | Log to standard output     | no        | no
+    \endtable
+
+    A list of fields can contain exact names or regular expressions.
+    The token '\@\@' in the result name is replaced by the name of the source
+    field.
+
+    The function object will skip over fields that would not benefit
+    - ie, only processor, empty, zeroGradient, symmetry patches.
+    This check should also prevent processing fields multiple times.
