ALTERNATIVE — FEKO
NO ALTAIR LICENSE
NO MoM/FEM MESH
BROWSER-NATIVE
The free FEKO alternative for WPT.
Altair FEKO is a method-of-moments (MoM) and full-wave EM workhorse — and overkill for early-stage inductive WPT coil exploration. AirInduct Sim covers the magnetostatic WPT regime that drives most FEKO coil-design projects, runs in your browser, and starts at $0.
01. · Why teams switch from FEKO
- No Altair per-seat license, no token-pool waiting room.
- No MoM mesh and no full-wave setup before the first inductance result.
- Eight WPT topology presets out of the box (Helmholtz, DTC, square, cross).
- Runs on any browser — Chromebook, iPad, phone, anywhere.
- Public REST API and MCP server for AI agents.
02. · Where FEKO still wins
Antenna design, radar cross section, full-wave radiation and large MoM scattering problems. AirInduct will get you to a candidate WPT coil in seconds; FEKO is where the radiation and antenna-pattern lap belongs.
03. · Migration path
Build and sweep your coil in AirInduct, export geometry and parameter sets, then drop them into FEKO for the final radiation / antenna-pattern pass.
