Was hoping Chuck or Don or another engineer would help us understand the simulation, but in my not particularly educated opinion, the value is in providing a visual illustration, rather than numbers.
I guess the scale has nothing to do with the yield strength of the frame.
IF however we knew the simulated pressure, we could know what percentage of that pressure was transmitted to the juncture of the frame.
And
IF we knew the thickness of the metal, and the tensile strength thereof, we could estimate the pressure that would crack the frame, in that failure is a function of pressure, thickness and tensile strength (and some other stuff).
Quite some time ago I had METL do composition analyses on some frames, including a Sterlingworth frame Michael send me. Unfortunately no Flues. If I had been smart, I would have had the machinist transect the frames (and they had tears in their eyes as they were cutting the frames for testing
) to measure the thicknesses. I gifted the frames to the machinists and engineers to use a paper weights so they are unavailable now.
The study is at the bottom here

I have a Parker frame, and if someone would like to send me a junker Flues frame I might just do that.
