We got tired of commercial EM simulators.
AirInduct Sim exists because modelling a WPT coil shouldn't require three different tools and a site licence. We built the simulation platform we wanted to use — physics-first, browser-based, and actually fast.
Model 8 coil topologies — 4 square, 4 circular — across every Helmholtz and distributed Tx / Rx combination. Sweep parameters, visualise fields in 2D and 3D, optimise with a genetic algorithm, and export to PDF, KiCad, DXF or SPICE.
Every field map is computed from the Biot–Savart law. Mutual inductance uses the Neumann formula. Self-inductance uses Grover's formulations for square coils and elliptic integrals (K and E kinds) for circular ones. No surrogate models, no curve fitting — every output traces back to a closed-form integral or its standard numerical reduction.
We don't ship a solver unless it matches the literature within tolerance. Our benchmarks include validation cases from four foundational papers:
