We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Sampat
I tried several simulation with different boundary condition. First I used the same model but with higher dimensions to have more radiation.
I also obtained temperature of 10^6 K, depending on the value of the heat flux. With Higher heat flux the simulation gives not coerent results.
I think that a boundary condition of heat flux on a high surface as in my model (high surface relative on the dimensions of the problem) is "too rigid". So this gives numerical problem on the simulation.
