Hi,
I've got a problem and don't find a solution with Google.

I want to simulate a light bulb like it was invented long ago. Many of you might know that one of the first light bulbs ever invented had no gas but vacuum inside and the wire was made out of platinum.
Now I try to simulate this state with Comsol with a little help of the light bulb which you can find in the model library (in Conjugate Heat Transfer).
But I don't know how to define the vacuum properly. I already know that the only Heat transfer in Vacuum is radiation but that doesn't help me a lot.

Thanks for helping me

regards
René
