Reply To: Heat Solver Simulation for periodic structure

1) Sorry again for the delay. My colleague has told me that I was mistaken earlier, we don't expect to see the results converge to a single solution when moving the fixed temperature boundary condition away from the device. In the example, it is assumed that the bottom of the substrate is fixed at room temperature and the entire thickness of the substrate is included in the simulation. The thickness of the substrate is an important parameter in this example, and has a significant impact on the results. If you'd like to take the same approach as the example, the entire thickness of the substrate should be included in the simulation region.
2) This example actually uses the same boundary conditions as the photothermal example, but from the temperature map results it looks like most of the heat is lost to convection in the air above the SiO2, so the x and y min boundary conditions have less of an impact on the results.
