Dear Community,

I am trying to analyze my system (combination of primary and secondary mirror) for a given temperature gradient. 

For that I have setup my LDE as shown in the below screenshot…

"Gradient 4" Surface is covering the whole system (PM and SM). Since I am working in Sequential mode. I have couple of questions…

1. Is LDE shown in the screenshot is correct if I want to study the effect of temperature gradient from Secondary mirror to Primary mirror (By changing Nx1 and Nx2 Value in Gradient 4 row focus spot shape is varying)?
2. Will the same temperature gradient be applied to the primary and secondary mirror as well, or it is restricted to the surrounding medium only?

Thanks.
