Hi @Marshdweller That's what I did when not using MFEM: using a set of edges in the mesh, which makes things much easier. Could you elaborate more how you did...

Thanks for the inputs @Marshdweller ! Is the class `VectorDeltaCoefficient` you were using ? I'm currently testing this but this is just an electric dipole, of course. The key problem...

@Marshdweller Nice picture, thanks ! I've done similar meshing with wire coincident with smaller edges. Could you elaborate how you handled the right-hand-size integration using MFEM functions ?
