Every number, traceable.
AirInduct Sim ships with a frozen benchmark suite drawn from the foundational papers of wireless power transfer. Each release is gated against a delta of ±5 % on every case — if accuracy drifts, the build doesn't go out.
No mesh, no convergence
We integrate Biot–Savart directly. There is no FEM mesh to refine, no relaxation parameter to tune, no sweep over element order. The same input always returns the same output.
Closed-form where possible
Self-inductance uses Grover's 1946 closed-form formulae for square and rectangular coils, and complete elliptic integrals (K and E kinds) for circular ones. Numerical integration only enters for arbitrary geometries.
Reproducible benchmarks
Every release runs against a frozen test set of 14 reference cases drawn from the four foundational papers below. A delta of more than 5 % blocks the build.
No black boxes
There are no surrogate models, neural nets or curve fits in the solver path. Every output traces back to a closed-form integral or its standard numerical reduction.

Every benchmark case ships with the simulator. From the dashboard, open Library → Validation suite and pick a case. The original paper, the published reference value, our simulated value and the delta render side-by-side.
