I like this classic explanation of the Git data model. https://eagain.net/articles/git-for-computer-scientists/ I've developed plugins for Git so know some obscure details and would be happy to discuss anything relevant to your work. You have my email if that's better or you'd like to switch to video.

Just a quick note that versioning as (UUID, integer) will lead to collisions as different people propose and share updates without a centralized authority to assign the integer revision. Like Git, unique hashes with parent references is a mature way to handle distributed versioning.

When you do a FEM calculation and you don't know about the materials then you are IMO in serious sh*t. I'd say not knowing "exact" material properties is typical, especially for composites, but also for plastic properties of metals (including with some heat treatments, etc.). Those proper...

Very nice!

Looks like in both the old and now cases, "0.3" is being parsed as float32 and converted to float64 before/when printing, thus the extra nonsense digits in Poisson ratio.

Is it in the purview of your work here to s/Father/Parent/?

Will the UUID change on each edit or only upon "creation"? What happens when a material is created and sent to a colleague, they edit parameters (like moduli, yield stress) and send it back. These are now two different materials with the same name. Are they related? Do they have the same o...

I would like to add material characterization support to FEM workbench (along with a new solver we've been developing). For that, I'd like a way to represent uncertainty in material parameters. In the simplest case, this might be a material with a nominal value and (max, min) bounds on elastic modul...

I see the issue with the constraint parameters dialog, one way to change it could maybe be to open the dialog, make the selection before pressing the Add button and then when pressing the Add bottom the existing selection would be automatically added... Yeah, just need to find where this logic is i...

Thanks, all. I modified the script to do selection based on a seed surface and bounding curves . E.g., in this example, select any one surface of the structure, then control-click to add each of the four curves (like the bottom left barely visible in yellow), and apply the macro (e.g., Control-Shift...

You mean something like shown in the following video for Ansys Discovery, where first the faces at the openings are selected (inlet and outlet) and then a "seed" face that represents the interior and then all the internal faces are selected and from it the internal volume is build... ? Th...

Ratel/. You can read about the methods in this paper, which tests scalability on hyperelastic analysis of Schwarz Primitive lattice structures with billions of DoFs.
