Hello, I want to simulate a coil of a transformer in Maxwell (3D), but my problem is: the coil design is not a closed path. Imagine that you draw a ring and then you cut part of it. You get something like a "letter C". In these two terminals I`m gonna put an excitation (100A, for instance), but it looks like maxwell do not accept a open path, just a closed one. Can anyone help me with this problem? Thanks!!
