    "description": "DC resistance of copper zone fills and traces between two contacts, single- or multi-layer with via coupling; current and power density maps.",
    "description_full": "Computes the DC resistance of copper zone fills and traces between two contacts (marker rectangles on User.1/User.2 and/or selected pads/vias), single- or multi-layer: the chosen net's fills and tracks are solved as coupled finite-difference sheets linked by the net's via and through-hole-pad barrels. Selected vias/THT pads inject at the drill-wall barrel, and every populated THT hole carries its full solder joint (component lead, solder fill, one-sided pad coat and protruding-lead cone) with exact pad shapes and do-not-populate flags read from KiCad, conducting in-plane as its solder plug and lead on every layer it spans. Every net pad's exact copper shape is stamped on the layers it sits on, SMD as well as through-hole, and oblong (slotted) holes are modelled as their true stadium shape rather than an approximating circle. Traces narrower than the grid become exact 1D resistor chains, and an adaptive multi-resolution grid (fine at features, coarse plane interiors, deferred-corrected) keeps large boards fast.\n\nShows per-layer rasterized maps, potential, current density and power density, reports per-via currents (via ampacity) and total dissipation at a selectable test current. An optional skin-effect correction (exact 1D foil/barrel solution at a user-set frequency) estimates the resistive skin rise only - proximity redistribution and inductance are not modeled, so this is not an AC impedance simulation. 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.",
