Error in Ansys Maxwell 2024R1 for WPT Coil (“Error in calculating the conducti)

[moral137]

I am simulating a WPT coil in Ansys Maxwell. It has Litz Wire.

The model was given as a STL file, I am able to setup the simulation but it runs out of memory.

I extracted the centerline of the cable an drew it myself inside Ansys (so the model is now composed of centerlines drawn by straight lines and then adding a circular crossection).

I am getting the following error (which I don't get with the STL file) : "Error in calculating the conduction paths. The most likely reason is that the mesh of the source conductor is wrong."

I have tried changing mesh settings (slide to make it finer and less fine), I pass the validation check, I can correctly identify the conduction paths. What could be going wrong here?

Thank you! I will be looking for any answers.

It's pointing at the conduction path, does it run through without error if you are using regular copper wire (not Litz)?

No, using copper generates same error.

Thanks for trying that, it might relate to the geometry. Can you make all three coils closed loops?
