Hello everybody,

These days I just tested the radiation models in OpenFOAM, as enlightend by this post:http://www.cfd-online.com/Forums/ope...n-problem.html

However, I found a few problems. One is that the view factor model seems to show no regards to 'empty' b.c. (I hope I am wrong here, but if I am indeed wrong I hope to corrected by you), which has been put in an independent post.

And regarding fvDOM, it seems you can only put your 2D geometry within X-Y plane. I took a look at the source code fvDOM.C and starting from line 88

       if (mesh_.nSolutionD() == 2)    //2D (X & Y)
        {
            scalar thetai = piByTwo;
            scalar deltaTheta = pi;
            nRay_ = 4*nPhi_;
            IRay_.setSize(nRay_);
            scalar deltaPhi = pi/(2.0*nPhi_);
            label i = 0;
            for (label m = 1; m <= 4*nPhi_; m++)
            {
                scalar phii = (2.0*m - 1.0)*deltaPhi/2.0;
                IRay_.set
                (
                    i,
                    new radiativeIntensityRay
                    (
                        *this,
                        mesh_,
                        phii,
                        thetai,
                        deltaPhi,
                        deltaTheta,
                        nLambda_,
                        absorptionEmission_,
                        blackBody_,
                        i
                    )
                );
                i++;
            }

So I don't know why OF developers do not consider other 2D situations.

Probably because of time/resources constraints...feel free to submit a patch!

How and where to do that?
