Hello everyone,

I'm trying to extract the leakage inductance value from a transformer using Ansys Maxwell 2D. As far as I know, there are two methods for calculating the leakage inductance: 1) Energy method, 2) Coupling coefficient method. I tried both methods on Maxwell 3D and they both gave the same leakage inductance value. Now I want to do the same on Maxwell 2D to get a faster result since I need to compare several different winding arrangements. However, the issue is when I use the methods on Maxwell 2D, the two methods give significantly different inductance values. Is there any other way to calculate the leakage inductance on Maxwell 2D?

I attached my 2D model of the transformer and the leakage inductance results from both methods.

Thank you.
