viewFactor radiation model
 

Dear Foamers,
I have 2 general questions regarding viewFactor radiation model.
1. Can this model be considered as an S2S (surface to surface ) only? Can it be compared say with s2s model in Fluent?
2. The openFoam tutorial is with this model is written for fluid-surface interaction and I found it to be quite complicated to start from. Can anybody share with me any simple case , which uses this model for a small number of surfaces (2 surfaces is an ideal case) , say two concentric cilinders or spheres or any other simple geometry.
Many thansks, Yuri

Dear Yuri,
I'm not really familar with the viewFactor model in Fluent, but there are some serious restriction with this model in OpenFOAM.
Take a look at the bug report:

And look for bug
