S2S radiation model

sagila · November 29, 2012, 16:29

Hello All,
Can I use S2S radiation model for the cavity as the figure?
When I use S2S radiation model, the solution does not converge. When I use DTRM radiation model, it converges. I don’t know what is the problem with S2S for this cavity!
Thank you.

I would appreciate if anyone could help me.

The S2S model is appropriate. Should work. Why isn't it working? I'm not sure.

Hi
I'm trying to model a combustion chamber by fluent, for considering its radiation I confront lots of problem which push my answers far from my experiments. at last I decided to use S2S model for its radiation but when I want to read the created file (view factors), Fluent could not read it and it shows an error.

Now I'll be appreciated if you could help me to make S2S setups or lead me to a proper radiation model.
