Class
    Foam::functionObjects::nearWallFields
 
Group
    grpFieldFunctionObjects
 
Description
    Samples near-patch volume fields.
 
    Fields are stored
    - every time step the field is updated with new values
    - at output it writes the fields
 
    This functionObject can either be used
    - to calculate a new field as a  post-processing step or
    - since the fields are registered, used in another functionObject
 
Usage
    Example of function object specification:
    \verbatim
    nearWallFields1
    {
        type        nearWallFields;
        libs        ("libfieldFunctionObjects.so");
 
        writeControl writeTime;
 
        fields
        (
            (p pNear)
            (U UNear)
        );
 
        patches     (movingWall);
 
        distance    0.13;
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property | Description               | Required    | Default value
        type     | type name: nearWallFields | yes         |
        fields   | list of fields with corresponding output field names | yes |
        patches  | list of patches to sample | yes         |
        distance | distance from patch to sample | yes     |
        log      | Log to standard output    | no          | yes
    \endtable
