Hello,

I am modelling a vacuum chamber which is cooled by LN2. Since it works in the vacuum I only have radiative heat transfer in it.

I have trouble to choose the correct operation and attribute features, depending on the ones I choose, the temperature I obtain on a specific place go from 100 to 200 [K].

I choose a stationary solver, the more credible results are with a stationary (linear) solver with coupled and iterative or direct attribute. However if I choose the same combination with nonlinear solver, I have strange results.
Finally when I choose segregated, all the results seem not credible.

Have you any idea how to justifiy the selection of these features?

Thank you very much!
