I want to simulate the electric fields in simple circuits using Python and only free software. My first goal is to reproduce the images given in (1) which are made by the commercial ANSYS Maxwell software. Where to start for such a project? Which libraries are suitable to attack this problem by solving Maxwell's equations numerically? And how to model and implement the circuit geometry?
I don't want a full solution but I am asking for a guide of how to attack this problem.
