My contribution there is a GUI frontend for using Tim Molteno's PyNEC library in a Jupyter notebook, so it does collect data on wire segments and radii and all that. My computations so far ignore most of the input data and just pull out the x,y coordinates, but it was a convenient interface I had available. My wire widget GUI project is described here: https://github.com/danzimmerman/n3ox_utils#wire-input-widget PyNEC is here, and is very interesting, especially for optimizations: https://github.com/tmolteno/python-necpp/tree/master/PyNEC I think PyNEC allows a huge number of segments and exposes some NEC features that I don't know are available outside of writing and executing raw NEC decks (which I am not really familiar with). I intended to add a PyNEC simulation to that notebook after I compute the currents, but unfortunately I had trouble last night installing and importing the PyNEC library in Google Colab. This issue doesn't seem to be PyNEC specific, many pre-installed Python libraries seem to be affected, so I don't know when or if that might be resolved :/ PyNEC is an extremely cool tool. I've found it challenging to install on Windows but I think it's usually very straightforward to install and use in a Python installation on Linux. The Colab issue is new. I had it working in Colab last year without issue.
