Class
    Foam::MarshakRadiationFixedTemperatureFvPatchScalarField

Group
    grpThermoBoundaryConditions

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

    The radiation temperature field across the patch is supplied by the user
    using the \c Trad entry.

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

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            MarshakRadiationFixedTemperature;
        Trad            uniform 1000;       // radiation temperature field
        value           uniform 0;          // place holder
    }
    \endverbatim
