I am doing magnetic field calculations for transmission lines using Maxwell, but I found that only when the boundary of the model coincides with the solution domain, can the current excitation be correctly allocated and the simulation run successfully. If the model is wrapped inside the solution domain, it will report an error. However, I saw a paper using Maxwell for magnetic field calculations, where his model was completely wrapped in the solution domain and could correctly calculate the magnetic field. How did he achieve this.

The figure below shows the Maxwell model and magnetic field calculation results from that article

The excitation must be closed loop or start & stop at region boundary in Maxwell. Both of the bottom pictures are created in Ansys Electronics Desktop, do you know what the excitation looks like in that model? Would it be possible a cross section view of XZ plane in your model?

Thank you,MirandaH.I have searched a lot of information and it is said that excitation should be start & stop at region boundary. These pictures are from a paper and do not mention how the excitation is set, only showing the model and simulation results from Maxwell. And the paper mentions that the simulation results are from a top view, which should be a cross section view of XY plane. It seems that only 8 solid wires are wrapped in the solution domain,so I really want to know how this was done.

Is that possible the wire is along z axis? start and stop at the z+ and z- region face
