1. Base case run with 12 kg dendrites burning (HFEFWindow1.xlsm). The heat source is 3 kg *150 kW/62.81 kg = 7.26 kW applied on the whole area. Pane A does not crack.

2. Base case with one half power for twice as long. (HFEFWindow2.xlsm). Decreased temperatures. Pane A does not crack.

3. Full power for twice as long (HFEFWindow3.xlsm). Increased temperatures in Pane A. Pane B small heat up. Stress not significantly increased in Pane A over base case. Stress in Pane B.

4. Concentrated heat flux cosine function heating (HFEFWindow4.xlsm). Center of heat flux centered on window. Stress is high enough that Pane A could crack. If Pane A stays in place, Pane B small heat up and small stress and will not crack.

5. Pane A disintegrated. Heat radiated directly to Pane B (HFEFWindow5.xlsm). Maximum was centered on center of window. Pane A and argon layer removed. Pane B could crack. If Pane A is open or removed, exposed material should be limited.

6. Maximum heat flux centered in location of the seal with Pane A removed (HFEFWindow6.xlsm). The seal would not degrade. Pane B could crack. If Pane A is open or removed, exposed material should be limited.

7. Maximum heat flux centered in location of the seal. Pane A in place (HFEFWindow7.xlsm). Pane A could crack. Pane B does not crack.

8. Pane A is assumed to break. Remainder of the heat is applied to Pane B (HFEFWindow8.xlsm). Pane A is assumed to break 1000 psi below the stress limit and is instantaneously removed. Remainder of heat is applied to Pane B. Pane B does not reach the stress limit and does not crack.
