Shape optimization / Topology In FreeCAD Tutorial

- čas přidán 26. 04. 2022
- Warning: This most likely wont work on any freecad version 20.0+ and I havent been able to get it to work in anything other than in version 19. If you still want to use this macro I would recommend downloading a version of freecad in the 19's. I will update here if the code is fixed. Sorry for this issue and I believe it is getting fixed.

It is incredible to see how far FreeCAD has come in the last 2 years.
Yeah, each update it just gets better and better. Excited to see what other updates and addons come out in the future.
I agree

The FEM workbench rocks. In version 0.15 was very hard to use and very limited.
Thank you so very much for making this tutorial. I'm doing a project on topological optimization for my school and just couldn't get it to work before watching your video.
You're an absolute life saver!
Hell yes! Fantastic tutorial, thanks so much for doing this. The only issue I had was not having the ccx binary installed on this computer before I began, everything else was just step-by-step.
Thank you!!, let me know if you have any outher ideas of things that need tutorials in FreeCad
Very nice tutorial, much appreciated. The script works just fine with FreeCAD 20.1.
I really appreciate your sharing this with the rest of us! Thank you.
The fixed supporting surface has partially disappeared. We need a way to explicitly select areas in the part that are not allowed to be optimized.
verry good
New geometries can be modeled using marching cubes and isosurfaces instead of manually.
This is really good topology optimizer! Github tutorial Example 3 you have written: "Then when Excract Surface filter and Triangulate filter are used, the mesh can be exported to the stl (File / Save Data)." I tryed to do so but I didnt managed to export mesh. Can you explain or make tutorial how to export optimezed mesh in stl format.
wow ❤❤❤❤❤❤ good
Brilliantly
Thanks for the tutorial! Is there any way to export the optimized mesh directly as a 3D-CAD model?
I did everything, I used freecad 20.1 and the current "beso-master" files. I imported the step file and defined the material. I did all the operations in the same way, but it gives a material error. I could not complete the analysis
This is the second comment I've seen for this issue. It might be a issue with the newer freecad version. I don't really know to much about how the code works so I recommend asking if they have a solution on their GitHub. If you find a solution please share.
@@ElevatedisScout I am currently thinking of using FreeCad version 0.19 as a solution, like you, I hope my problem will be solved.
@@musamakine1073
To use the beso algorithm I thinks you explicitly have to tell FreeCAD that the material is a solid.
At the bottom of the material object, select the whole body and indicate that is a solid
Thanks for the video, but I when I try to generate I get an error. I followed every step, and it still didn't work. No idea what to do. Maybe because I am running an AMD CPU and GPU.
I used the same setup. I'll re try it later today and make sure it still works
Be sure to define the model as a solid in the material section
Followed step to step but I always get this error no matter what model I try. Could you please help me understand this. I am using FreeCAD 0.20.2

Honestly I dont know much about coding and would suggest posting in r/freecad on reddit or on the github I linked in the description. It sound like freecad 20 and above is having issues with it. This video was on version 19. something and I believe that something in the code must have changed which messed up this macro and that the people who created it on github must adjust their code. I will add a warning to the description about this for future people.
@@ElevatedisScout thanks a lot for the reply. I tried with version 19 and still does not work. Does not seem a version issue.
@@akhil7650 Did you solve your issue? I can't get it to work either, even on ver 19.
Yes, you have the beso files in the drive you have your freecad installed. No issue with the versions. I don't know if it's general knowledge but yes works now.
@@akhil7650 even in version 20?
Has the code been fixed for freecad version 20.0+?
