I have two concentric coils, carrying currents in the opposite directions from each other. I create cross-sections and assign coil terminals to them (in the opposite directions), and add them to a winding. My results have been inconclusive so far. The inductance values obtained from the "Matrix" in an "eddy-current module" gives me a value which does not seem right. I even tried increasing the number of adaptive passes for the convergence to a finer mesh, but it's the same thing.

Just yesterday, I discovered "Join in series" and "Join in parallel" options when I right clicked "Matrix", which gave me the ability to join multiple windings in series/parallel.

Hi @S78MALIK In your model since both the coils are not physically connected. Adding each of them to a separate winding is enough. You need not select join in parallel or series.
After the matrix computation, you will get self, mutual and leakage inductance values in the results.
When you say "value which does not seem right" - What are you comparing the results with?
I don't know how did you set up everything in the model.
If multiple coils are added to a winding, Maxwell assumes all those coils are connected in series.

Hi @Navya,

Could you tell me how to parallel the current source in Maxwell 3D eddy current solver?

I have a transformer and I want to parallel the secondary side, but I don't know how to parallel it.
