Class
    Foam::MarshakRadiationFvPatchScalarField

Description
    A 'mixed' boundary condition that implements a Marshak condition for the
    incident radiation field (usually written as G)

    The radiation temperature is retrieved from the mesh database, using a
    user specified temperature field name.

Usage
    \table
        Property     | Description             | Required    | Default value
        T            | temperature field name  | no          | T
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            MarshakRadiation;
        T               T;
        value           uniform 0;
    }
    \endverbatim
