I'm not sure what error you are referring to, but if you are having trouble running this macro with FreeCAD, make sure you close everything after you open the macro with FreeCAD for the first time. Once you have done this, open FreeCAD again and then open the macro. This should enable the Material Object to be recognized (here as Material Solid). Also, check that your mesh is correct. I hope this be helpful.
I am glad the example was helpful. Yes, I tried it with a cube and it works as well. The link below shows a picture of topology optimization results of a cube. drive.google.com/file/d/1wCsDnOF8jSJE7Ma_1W6DM-DuBTaKBFgZ/view?usp=share_link
When I tried to run the macro as shown in 11:30, I received the error "UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 86: character maps to ". I tried restarting FreeCAD, but the issue persists. I am using FreeCAD 0.20.2. Thanks for any help! Very interesting video!
A very nice and illustrative video abt Topology Opt and Python!
Thanks for your comment, I am Glad you liked it!
Much appreciated, I look forward to working through more of your work.
I am glad that these tutorials are helpful and inspire you!
Really useful. Please keep these tutorials coming!
Thank you for your positive feedback, I will continue these tutorials!
An excellent video. Thanks for the effort you've put into this! I'm looking forward to viewing the entire series.😄
Great, thank you for following and supporting this channel!
Great example, well illustrated 👍🏻
Glad to hear it! Thanks!
Hello! Does it work with FreeCAD 1.0 and above?
This video is very helpful! What is the type of stress it lets us to define as a limit for the optimization process?
I am getting an error of no such directory found for file000.dat. Could you please help? Thank you.

@@Engr4all hey, thanks for the reply. It resolved when i put the macro files in C where freecad is installed.
I am glad to hear that you were able to resolve the issue by putting the macro files in the installed FreeCad location.
Good Luck!
This is very good example. I would like to ask if the macro will work for also for a part that will be like more in 3D, like a cube shape ?

You should replace the \ with \\ or use r"C:\\..."
@@YuriyUvarov totally good now! But I found that topology optimization in Python (on Google Colab) is much faster than in FreeCAD :)
