The only platform that takes you from coil geometry to coupling factor to CAD export in a single, instrumented session.

01 · FIRST-PRINCIPLES SOLVER
Real physics. Real speed.
Vectorised Biot–Savart, Neumann mutual-inductance and elliptic-integral kernels — no FEM, no meshing, no convergence babysitting. A 100 × 100 field map returns in roughly two seconds; a 50³ volume in fifteen.
02Eight topologiesFig. 02 — Eight calculators, one engine
02 · EIGHT TOPOLOGIES
Square and circular, Helm and DTC.
Four square and four circular geometries — Helmholtz–Helmholtz, DTC–Helmholtz, Helmholtz–DTC and DTC–DTC, in both shapes. Each pair has a dedicated calculator with topology-specific input ranges.

03 · THREE RENDER MODES
2D, vector, volume.
Switch between a 2D plane heatmap, a downsampled vector-field overlay and a full 3D isosurface volume — all driven by the same H-field tensor. LOD levels 0/1/2 trade detail for a 4× speed-up on heavy grids.

04Parameter sweepFig. 04 — Pre-computed sweep frames over one period
04 · PARAMETER SWEEP
Animate the parameter space.
Sweep any of the thirteen tunable inputs — current, frequency, turn count, spacing, coil size — across 2 to 100 steps. Adaptive mode auto-generates ~300 points for smooth efficiency curves. Frames return as a JSON array, ready to scrub.

We show our work.
Mutual inductance benchmarked against Babic & Akyel (IEEE Trans. Magnetics, 2008) at 1–2 % for coaxial pairs. Self-inductance against Grover (1946). SS and LCC-LCC matching against Kurs et al. (Science 2007) and Covic (IEEE TPE 2013) at ±3–5 %.

Persist coil geometries to your personal library and pull them into any of the eight calculators. CSV import for migration from a spreadsheet; bulk edit for parameter studies.

07Genetic optimiserFig. 07 — Convergence and Pareto search
07 · GENETIC OPTIMISER
Geometry that finds itself.
A micro-GA with BLX-α crossover and tournament selection (k = 3) runs 80 generations of population 40 to hit a coupling target. Multi-objective mode returns an NSGA-II-style Pareto front over k, η and power.

08ExportFig. 08 — Four artifacts from one session
08 · EXPORT
From session to fab.
Every run exports four ways: a typeset PDF report, a KiCad PCB footprint (.kicad_mod), a DXF outline for downstream CAD and a SPICE netlist with the L · M · k component values for circuit simulation.

09Web · mobile · desktopFig. 09 — Same engine across web, mobile and desktop
09 · WEB · MOBILE · DESKTOP
One engine, three surfaces.
Run from the web dashboard, the iOS & Android app, or the native macOS / Windows / Linux desktop build. The 6.78 MHz ISM and 85 kHz SAE J2954 bands ship as presets; arbitrary frequencies up to 1 THz are supported.
