Great. Thank you so much!

Oh, that's interesting. I find it surprising that they're so different.

Thank you!

Ah, maybe the AV solver is using the potential to infer the current and the using that to produce the magnetic field?

magfield.png Excellent! I changed: Body Force 1 Name = "Body forces for copper" Electric Potential = Equals "Potential" End And I think that's closer. I don't understand why there are two current densities: current-density.png However, the magnetic field is doing the right thing...

Thank you! I'm not sure how to interpret the 2D case. Maybe I'm running the solver incorrectly? This is what I see for potential. potential.png I was expecting one end of the trace to be at a higher potential, and the other end lower. I just added an ELMERSOLVER_STARTINFO file and ran ElmerSolver. I...

The getting started document was very helpful. Thank you for pointing that out! I did add the fragment and coherence statements to the GMSH script. However, it's still diverging on the WhitneyAVSolver. BiCGStabl: 188 0.4524E+21 0.4524E+21 ERROR:: IterSolve: Numerical Error: System diverged over maxi...

Excellent. Thank you again! I'll give that a try.

Yes, the dimensions in the .geo file are meant to be in mm, so 1e-3 is the correct scaling factor.

I have to confess, I have no idea what you mean by "fragment" and "coherence". No doubt I'm missing something important. I'll try to track down documentation about that.

thank you!

Thank you kevinarden! You've gotten me moving forward. Unfortunately I'm still not quite there, but I'm encouraged! I am working towards a setup similar to the "End Windings" example from Elmer-Elmag (see previous post). I got the static current calculation to work pretty well, but I notic...

Thank you so much!
