24 Class
25     Foam::nearWallFields
27 Description
28     Samples near-patch volFields
30     Holds fields
31     - every timestep the field get updated with new values
32     - at write it writes the fields
33     so this functionObject can either be used to calculate a new field
34     as a postprocessing step or (since the fields are registered)
35     use these in another functionObject (e.g. faceSource).
37     surfaceValues

39         type        nearWallFields;

41         enabled         true;
42         outputControl   outputTime;
43         ..
44         // Name of volField and corresponding surfaceField
45         fields      ((p pNear)(U UNear));
46         // Name of patch to sample
47         patches     (movingWall);
48         // Distance away from the wall
49         distance    0.13;   // distance away from wall
