Re: Shell Solution Elmer

You only need the Elasticity equation and the mesh has to be created with Gmsh. You should also define thickness with FEM ElementGeometry2D. But Elmer has some serious limitations regarding solid mechanics and this configuration may not work. I would just use CalculiX instead.

Re: Resize hole

It depends on how the holes were created. The PartDesign Hole has the benefit of being able to easily modify the hole parameters. But if you created the holes by just applying Pocket to a sketch then you should modify the sketch (and Pocket if needed).

There is also Cfd workbench but it’s abandoned while CfdOF is actively maintained: https://github.com/jaheyns/CfdOF You can f...

Re: how do devs keep the software reliable and safe?

In the case of FEM, the answer is simple - that’s what benchmarks are for. Like those published by NAFEMS. FreeCAD uses 3rd party FEM solvers but you can follow this thread to see how it can be done when developing a solver from scratch: https://forum.freecad.org/viewtopic.php?t=85474 Another thing ...

Bug tracker button on the forum

Hi,

the bug tracker button on the top bar of the forum still leads to the old Mantis bug tracker. Can someone replace it with a GitHub issues section link ?

@kkremitzki ?

Re: Can't constrain spline [newbie needs help pls]

A sketch can still be extruded even if it's not fully constrained. But here you are just missing constraints (can be just horizontal + vertical w.r.t. the origin) on the two rightmost spline control points.

Re: How to install FreeCAD on Ubuntu 22.04 with gmsh for FEM

I would just download Gmsh from here: https://gmsh.info/bin/Linux/gmsh-4.12.2-Linux64.tgz, unpack it and point FreeCAD FEM to it in Edit --> Preferences --> FEM --> Gmsh --> Gmsh binary path.
