Joule Losses in Volume Regions
Hi,
I am modeling a synchronous permanent magnet motor with Flux 3D and wish to compute Joule losses in multiple contiguous volume regions corresponding to the magnets and the bracing circling the magnets. So far I have tried two strategies:
- assign solid conductors regions to these volumes and couple them with a solid conductor electric component and then create sensors to compute the Joule losses on the circuit components
- assign magnetic non-conducting regions to these volumes and then create sensors to compute Joule losses on the volume region
In Flux 2D, the first strategy was effective and produced satisfying results but in 3D, it leads to an error interrupting the solving shortly after it starts.
The second strategy seems to produce inconsistent results: the computed Joule losses are always null.
I would appreciate any help in resolving this issue and thank you in advance for your assistance.

Hi,
To compute the Joule losses in the magnet you need to use a soldi conductor region. You don’t need to couple this with a circuit. Just put the solid conductor region and the material (with the resistivity).
When you do check physics, Flux display an error message?
Best regards.

Hi,
Thanks for the tip, it seems to have done the job!
The weird thing is that everything was ok after I did Check Physics. But only shortly after the beginning of the solving did Flux interrupt it. An error message said that electric terminals could not be correctly assigned to contiguous volumes of solid conductors region type.
But without coupling with the electric circuit it works!

Hi,
did you assigned an electrical terminals to solid conductor region?
Can you share your project (zip format without mesh).
Best regards.

Hi,
Yes, I did. I assigned electric terminals to the solid conductor volume regions because these regions were coupled with an electric circuit. After removing the circuit, as you recomended, I no longer needed to assign electric terminals and the solving process went through.
I think the issue is resolved now anyway, the results provided by the sensors are fine.
I am sorry, but I'm not allowed to share project files.
Regards,
