The simulator built for WPT.
AirInduct Sim is a purpose-built wireless power transfer simulator that runs in your browser. No mesh setup, no quote-only pricing, no half-day install. It uses analytical Biot–Savart and Neumann kernels to solve the coil-design regime that general-purpose FEM tools spend most of their time on — only faster, free, and validated against the foundational WPT literature.

You are designing wireless power coils — primarily air-core, primarily inductive, in the 85 kHz – 13.56 MHz range — and you want answers in seconds, not after a meshing tutorial. Examples: SAE J2954 EV pads, biomedical implant power links, IoT sensor charging, academic WPT coursework, prototype review with non-engineers.
Heavy ferrites, exotic conductors, multi-physics (thermal + structural + EM coupled), radiated emissions above tens of MHz. AirInduct exports geometry and parameter sets you can take into Ansys or CENOS once a candidate design is dialled in.
