Huge list of engineering FOSS
With links for each, and sorted into categories. Largest category being finite element analysis (FEA) and computational fluid dynamics (CFD) simulation solvers which are used for things like stress, thermal, electromagnetic simulation etc. Also some CAD and general tools
Anyone have shortcuts for modeling complex over center, compliance mechanisms, and bistable auxetic materials? I'm using FreeCAD and trying to just use rough sketches and trial and error to create a bending tube structure that 3d prints vertically but then bends into place like a pop-tube kid's toy, but only on one side of an otherwise vase mode print design. I'm really pushing the limits of what FreeCAD can loft before edges go wonky and the Part Design workflow is no longer sufficient. I can make a compliant spring easily, but a bistable bend in a tube is at the edge of my learning curve.
There’s a professor and his research group at university of Michigan that does compliant mechanisms that u could check out if they’ve got something. It was a while ago that I applied there so possible he moved but still worth a check.
I’ve never used freecad as I’ve always had access to a cad program thru either school or work. One option that’s not free is to join a maker space that has better cad programs or just torrent. But you’re definitely in need of FEA for the bistable part
The open toolchain foundation also has a similar list I think
