Dear all.

I have tried to modify radiativeIntensityRay.C .
But i have a question.

// * * * * * * * * * * * * * * * * Constructors  * * * * * * * * * * * * * * //

Foam::radiation::radiativeIntensityRay::radiativeIntensityRay
(
    const fvDOM& dom,
    const fvMesh& mesh,
    const scalar phi,
    const scalar theta,
    const scalar deltaPhi,
    const scalar deltaTheta,
    const label nLambda,
    const absorptionEmissionModel& absorptionEmission,
    const scatterModel& scatter,
    const blackBodyEmission& blackBody,
    const label rayId
)
:
    dom_(dom),
    mesh_(mesh),
    absorptionEmission_(absorptionEmission),
    scatter_(scatter),
    blackBody_(blackBody),
    I_
    (
        IOobject
        (
            "I" + name(rayId),
            mesh_.time().timeName(),
            mesh_,
            IOobject::NO_READ,
            IOobject::NO_WRITE
        ),
        mesh_,
        dimensionedScalar("I", dimMass/pow3(dimTime), 0.0)
    ),
    qr_
    (
        IOobject
        (
            "qr" + name(rayId),
            mesh_.time().timeName(),
            mesh_,
            IOobject::NO_READ,
            IOobject::NO_WRITE
        ),
        mesh_,
        dimensionedScalar("qr", dimMass/pow3(dimTime), 0.0)
    ),

1. What is the meaning of rayId ??
2. Why is name(rayId) added to "qr" and "I" ??

Thank you in advance for answering.
Best regards and have a nice day.

I think rayId means 'ray i direction'.

Is is correct??
