I am trying to simulate something that is somewhat similar to the given DriftTube example. What I want to do is to have a cathode plate on the bottom, some anode wires (3) above the plate, and in the drift region between the anode wires and the cathode plate, there will be rectangular loops of wires that encompasses the whole drift region (picture is attached). Adding the anode wires is easy, I can just use the AddWire function, but for the loops of wire and the cathode plate, I am having some trouble with. I would like some help on how to do this or at least where I can look up information on how to do this.
I am still reading the user guide, so if there is specific region that I need to focus on, please let me know. Also, the loops of wire does not necessarily be one continuous piece of wire. Instead it can be four segments adding up to make a rectangle. Thank you in advance.
