Class
    Foam::greyDiffusiveViewFactorFixedValueFvPatchScalarField

Description
    This boundary condition provides a grey-diffuse condition for radiative
    heat flux, \c qr, for use with the view factor model

Usage
    \table
        Property     | Description             | Required    | Default value
        qro          | external radiative heat flux | yes    |
        emissivityMode | emissivity mode: solidRadiation or lookup | yes |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            greyDiffusiveRadiationViewFactor;
        qro             uniform 0;
        emissivityMode  solidRadiation;
        value           uniform 0;
    }
    \endverbatim
