OOPS ...

Code: Select all

<class 'ModuleNotFoundError'>: No module named 'scipy'
I thought this was a standard FC dependency.


And I see I also missed "sksparse" for the solver.

Sorry

Fixes incoming:

Set path to Gmsh exe automagically: https://github.com/FreeCAD/FreeCAD-snap ... 8e8d3bb8e1
The /dev/shm issue has been solved by https://github.com/FreeCAD/FreeCAD-snap ... 0b2fcd69a8
scipy: https://github.com/FreeCAD/FreeCAD-snap ... 16ca99feff

Try it tomorrow.

Ah, and also: If you encounter problems or deficiencies with the snap, please report them at https://github.com/FreeCAD/FreeCAD-snap/issues if possible. It's a much better tracker for me than the forum, and therefore stuff usually gets fixed quicker.

Looks good. I'm always quite flexible about those requests. :D

This will land in latest/edge (and in latest/edge/toponaming) tomorrow.

@HarryvL It's great that fcFEM will be developed again. FreeCAD may benefit significantly from having a solver designed specifically for it.

Do you plan to keep updating the GitHub repository ?

Hi, yes is the short answer.

I will get a standard/basic version ready first (that can reproduce most cases of this thread), with a set of test cases, as was asked for.

After that I will reinstate a specialized version for concrete and further develop that into a robust tool for conceptual design.

What experimental versions come after that is only limited by time, ideas, requests and feasibility.
