Hi.
I am trying to simulate the heating of a piece of glass due to the action of a lamp made of a array of 7x7 leds. The piece of glass it is under 50 mm from the lamp.
This is to compare with experimental data.
To do it, I have been used the model called "rapid thermal annealing" of the model library as a guide.
In the solutions I can see the evolution of the temperature in the lamp, but the piece of glass is always at the same temperature (initial T). It is like if the lamp does not heat the glass.
I need to know where could be my error building this model. Could someone help me?
Thanks.

Since heat can only reach the glass in your model via radiation, then check the surface-to-surface radiation definitions.
