Most likely is that it was deemed simplified enough not be an issue?
Did Sandia use a thermonuclear secondary in a product logo?

#12Basically 0 CAD models you see with color coding and a mesh are actually accurate.
In order to mesh the geometry for finite element analysis, the geometry virtually always needs to be defeatured.
So the cross sectional CAD model here is a nice curiosity but basically useless for any reverse engineering purposes which is the key reason this stuff is kept secret.

#13I see a few commenters think the big chart/diagram in the first picture is the one being discussed. It is not, it's the rightmost slice ("Salinas") of that infographic which shows something like a warhead. It's shown blown up (pun intended) in the second picture of the article.

#15For everyone complaining that it's an infographic, not a logo, that's addressed in the article:
> It’s literally the logo they use for this particular software package.
Which seems to refer to the image of the re-entry vehicle in isolation from the infographic where the author originally found it.

#16Why someone is calling a chart/diagram a logo is the bigger mystery here. Mockups of things exist.
It's not a diagram or mock-up, it's a direct representation of the real thing for computer simulations, similar to CAD. The dimensions and shape of the components are accurate. And the author is calling it a logo because the picture is used to represent and advertise the software.

In Germany we say "The DIN knows non color". DIN is our standardization organization and informally also how their documents are called.
I did finite element model preparation for a living many year ago and it did not only involve heavy defeaturing but interestingly also remeshing with quads.
Renderers love triangles, FE solvers love boring quads.

It's a product diagram on a presentation slide. Hopefully meant to be read on handouts or proceedings.
A logo is the Sierra stylized text in the lower center.
And the two others in the slide's footer.
That Sandia might use, what was obviously intended as a diagram as a logo is a whole other thing but doesn't make it one.
As long as all representation of that thing are that big and readable one can assume they were not used as logos.

#19This thing could be a test object that doesn't work as an actual nuclear warhead but is similar enough to validate the discussed software: real-world crash tests match software simulations, and being accurate at simulating the dummy is a guarantee of being accurate at simulating classified weapon designs.
