Class
    Foam::functionObjects::wallHeatFlux

Description
    Calculates and write the heat-flux at wall patches as the
    volScalarField field 'wallHeatFlux'.

    All wall patches are included by default; to restrict the calculation to
    certain patches, use the optional 'patches' entry.

    Example of function object specification:
    \verbatim
    wallHeatFlux1
    {
        type        wallHeatFlux;
        libs        ("libfieldFunctionObjects.so");
        ...
        region      fluid;
        patches     (".*Wall");
    }
    \endverbatim

Usage
    \table
        Property | Description                | Required   | Default value
        type     | type name: wallHeatFlux    | yes        |
        patches  | list of patches to process | no         | all wall patches
        region   | region to be evaluated     | no         | default region
    \endtable

Note
    Writing field 'wallHeatFlux' is done by default, but it can be overridden by
    defining an empty \c objects list. For details see writeLocalObjects.
