ALTERNATIVE — ANSYS
NO LICENSE
NO INSTALL
BROWSER-NATIVE
The free Ansys WPT alternative.
Ansys is excellent for general-purpose electromagnetics — and overkill for wireless power coil design. AirInduct Sim covers the inductive WPT regime that drives most Ansys Wireless Charging projects, runs in your browser, and starts at $0.
01. · Why teams switch
- No quote-only enterprise license — free tier runs the full solver.
- No 30-minute meshing setup before the first result.
- Eight WPT-specific topology presets (Helmholtz, DTC, square, cross) instead of a blank canvas.
- Runs on a Chromebook, an iPad, a phone — anywhere a browser runs.
- Public REST API and MCP server for AI agents — no scripting license.
02. · Where Ansys still wins
Coupled multi-physics (thermal · structural · EM), heavy ferrite cores, radiated emissions above tens of MHz, full-system EMC. AirInduct will get you to a candidate coil design fast; Ansys is where the production-validation lap belongs.
03. · Migration path
Build and sweep your coil in AirInduct, export geometry and parameter sets, then drop them into Ansys Maxwell or HFSS for the final certification pass. The two are complementary, not redundant.
