AirInduct Sim, without the browser.
The full simulator — eight topologies, three render modes, the genetic optimiser, sweeps and exports — packaged as a native desktop app. Built for heavier sessions, offline work and direct file-system access.
Pick your platform
Three operating systems, six builds. v1.4.0 released 2026-04-15.
macOS
Windows
Offline runs
No network round-trip. The Biot–Savart kernel runs in-process; results land in milliseconds even on long flights.
Heavier sessions
Push to the full 100 × 100 × 100 volumetric grid without queue limits — your CPU is the only ceiling.
Direct file access
Save / open .coil JSON files from disk; export PDF, KiCad, DXF and SPICE straight to your project folder.
Auto-update
Signed updates ship in-app. Stay on the latest engine without a fresh install.
Code-signed
macOS notarised, Windows EV-signed, Linux GPG-signed. Verifiable provenance for procurement reviews.
Same engine
Bit-for-bit results match the web and mobile apps — IEEE-validated against Babic, Grover, Kurs and Covic.
