Class
    Foam::radiation::opaqueDiffusive
 
Description
    Radiation boundary model for opaque diffusive walls. It requires to
    specify a wallAbsorptionEmissionModel in boundaryRadiationProperties
    file.
 
Usage
    \verbatim
 
        type       opaqueDiffusive;
        wallAbsorptionEmissionModel
        {
            type            multiBandAbsorption;
            absorptivity    (0.3 0.7);
            emissivity      (0.3 0.7);
        };
