At a user-set frequency the exact 1D foil/barrel skin-effect correction is applied (AC results are a rigorous lower bound). PNGs, a text summary and a re-solvable geometry dump are saved per run.\n\nNote: the first load builds the plugin's Python environment (numpy, scipy, pyamg, matplotlib, PySide6) and can take several minutes.", "identifier": "th.co.b4l.fill-resistance", "type": "plugin", "author": { "name": "janik", "contact": { "email": "oltmanns@b4l.co.th" } }, "license": "GPL-3.0-or-later", "resources": { "homepage": "https://git.b4l.co.th/B4L/kicad-zone-resistance" }, "versions": [ { "version": "1.0.0", "status": "stable", "kicad_version": "10.0", "runtime": "ipc" } ] }
