Changelog
Recent changes to the app, downloads, tutorials, documentation, and supported workflows.
Updated July 14, 2026.
RPL Engine Workbench is now available as an unsigned Windows 11 (64-bit) public beta installer with the built-in trial and the shared solve, export, and Flowfield Studio workflows. The download page lists its size, SHA-256, and SmartScreen guidance. The Apple silicon Mac release remains version 1.0.0, signed and notarized.
Simplified how you get started: download the Mac app and run it in built-in trial mode — no license key required — then buy a Personal or Business license directly from the pricing page.
The site now includes reference material: articles, methods, validation context, legal information, a glossary, and documentation. Navigation and the overall visual design were refreshed.
Current tutorials cover case setup, propellants and chamber targets, nozzle sizing, DXF export, injector sizing, Flowfield Studio, transient playback, residual review, reports, media export, appearance settings, and trial and license activation.
RPL Engine Workbench is offered as a native Apple silicon Mac application for pressure-fed engine design, geometry export, reporting, and integrated Flowfield Studio visualization.
