Hey,

I tried to carry out a heat transfer analysis. I created several blocks of different materials. I defined:

- material models from a library, all of them had thermal properties defined
- contacts: bonded
- Initial temperature for all surfaces: 20 degrees
- boundary condition temperature on one surface: 700 degrees
- loads: radiation 0.5

And I added models such as the boltzman constant. The problem is that the obtained results are not correct. The lowest temperature is below zero. I tried doing a steady-state analysis and the results were already correct. Where should I look for the problem? I have attached screenshots of the results and boundary conditions
