Re: Begging for help regarding temperature FEM analysis
the topic is not solved if the errors are fixed! The topic is about pcb FEA modelling!

Re: Begging for help regarding temperature FEM analysis
Hello all,
thanks for all your response and work that has been spend.
I'm trying to get an updated version but on that page its still 0.19.19858:
https://github.com/FreeCAD/FreeCAD/releases
Where do I get the mentioned 0.19.19946 from?
Thank you.

You must wait till the next update. Each OS package is generated separately from the rest and at different timeslighting_freak wrote: ↑Sat Mar 07, 2020 8:59 pm Where do I get the mentioned 0.19.19946 from?

Re: Begging for help regarding temperature FEM analysis
wait just some days, may be after the weekend ...

You can also try to Compile on Docker I understood from a recent post that it now supports FEMlighting_freak wrote: ↑Sat Mar 07, 2020 8:59 pm Hello all,

Re: Begging for help regarding temperature FEM analysis
Hi,
just downloaded the new windows dev-release and I can confirm the errors are gone!
Thanks for that quick effort once more.
Let's come back to the main topic.
From LED datasheet one can see that this type consumes 0,15 Ampere x 9,80 Volts = 1,47W
In worst case I'd like to assume that this 1,47W are fully converted into heat...
From my current understanding the LED solder pads should be the faces carrying this heat flux, but I can't reach this faces after building the "compound" - object any longer. How is the process for correctly defined faces that are in touching condition?
EDIT: I tried also the "fragmented boolean" option - but in that case the mesh fails due to identical faces...
EDIT: I'm also willing to change the CAD model itself, if necessary. For example I could prepare a surface model that has only a single face in touching areas (often like this in lighting). So if it helps, just let me know.
There is the geometry and the current FEM setup... The "constraint temperature" is wrong. Due to the issue above I simply selected the face of the resin for heat flux definition.
By the way, while saving a FreeCAD project file from time to time this message appears:

Re: Begging for help regarding temperature FEM analysis
Hello all,
Thanks for taking care of the error messages.
What's about the initial question about the "how to"?
Thank you.
