Is there a modern free alternative to Ansys Maxwell SV?

Yes — AirInduct Sim is a modern, browser-based, full-3D alternative to the discontinued Maxwell SV for the inductive WPT regime. Closed-form Biot–Savart, no install, no Windows requirement, no mesh.

Why migrate off Maxwell SV?

Maxwell SV is no longer supported, runs only on legacy Windows installs and is limited to 2D / axisymmetric. AirInduct delivers full 3D B and H fields in any modern browser.

Will AirInduct match the inductance and coupling values I got from Maxwell SV?

For the inductive WPT regime, yes — AirInduct typically agrees with Ansys Maxwell (SV and the modern Electronics Desktop) within 1–2% on coupling coefficient and inductance, validated against published WPT benchmarks.

ALTERNATIVE — MAXWELL SV

MODERN

WEB-NATIVE

3D NOT 2D

The modern Maxwell SV alternative.

Ansys Maxwell SV was a beloved free 2D solver — but it's discontinued, Windows-only and limited to 2D. AirInduct Sim is its modern, browser-based, full-3D, WPT-tuned successor. Free, no install, no mesh.

01. · Why move off Maxwell SV

Maxwell SV is discontinued — no support, no updates.
Windows-only legacy install vs. browser-native AirInduct.
2D / axisymmetric only vs. full 3D B and H fields.
Eight WPT topology presets (Helmholtz, DTC, square, cross) out of the box.
Public REST API and MCP server for AI agents.

02. · Where modern Ansys Maxwell still wins

Coupled multi-physics, nonlinear ferrite cores, large-scale assembly EM. AirInduct is the fast first-pass tool; modern Ansys Maxwell remains the production-validation step.

03. · Migration path

Recreate your Maxwell SV coil in AirInduct (eight built-in topology presets cover most legacy designs), then sweep parameters in seconds and export to KiCad, DXF or SPICE.
