Hi Peter,

I am using ANSYS 2021 R2. I really appreciate your availability and I accept that help, as I am not exactly familiar in setting up 2D Axisymmetric models.

For the diamond, I'm using:
E = 1000 GPa
v = 0.07
d = 3520 kg/m3

From my last approach modelling the window as a surface, I could get stress results that well agrees with the analytical solution for thin plates model, and from them it seems that a fixed edge boundary condition has lower maximum stresses than a simply supported one. I need to look further into that assumptions, but it seems that glueing the window would be indeed a nice solution.

Then I would need to start thinking on how to include the glue in the simulation, and that's a whole other field which I don't have any experience 😅
