PCB thermal analysis revisited

[gerhard63]

In the last days I started to dig into the FreeCAD world of thermal simulation of pcbs.
After a lot of tries to get a kicad pcb into freecad with KiCadStepUp, I found this thread and fcad_pcb from @realthunder.

Unfortunetally Im not able to start the scripts. It stopps running with the the following error message:

2023-01-07 16_29_39-FreeCAD 0.20.1.png (15.73 KiB) Viewed 1300 times

Does any one know about this problem?
I spent nearly the whole day without any success...

Thanks in advance.

from your errors it seems you have an outdated fcad_pcb release version

[gerhard63]

I used the version from Feb 18th, 2020 downloaded here:
https://github.com/realthunder/fcad_pcb ... es/tag/1.1

Where can I find the latest?

That is 3 years old...
you have to download directly from GH
Please follow instructions on readme

With windows I cannot use git and clone.
I download all files and put it unchanged into the macro directory, correct?

https://gitforwindows.org
or
https://git-scm.com/downloads
then git clone it in the downloading directory and follow the readme commands

Hi easyw-fcw

The phyton script is running now correctly. But with max. 2 layers. Multilayer seems not tobe supported.

However...
Thanks for your help.
