Class
    Foam::fixedMeanFvPatchField
 
Description
    This boundary condition extrapolates field to the patch using the near-cell
    values and adjusts the distribution to match the specified, optionally
    time-varying, mean value.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        meanValue    | mean value Function1    | yes         |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            fixedMean;
        meanValue       1.0;
    }
    \endverbatim
