Native builds for Windows 11 (64-bit) and Apple silicon macOS. Both start in built-in trial mode with no license key; a purchased key later activates the complete product in place. It is one product and one purchase — download the build for the computer you run.

Signed by Rocket Propulsion Laboratory LLC and notarized by Apple, so it opens without the unidentified-developer warning on a standard Mac.
RPL Engine Workbench 1.0.0 Windows x64 Beta Setup.exe.Verify the download in PowerShell: Get-FileHash -Algorithm SHA256 "RPL Engine Workbench 1.0.0 Windows x64 Beta Setup.exe" — the value must match the Windows SHA-256 below.
.dmg. The app is notarized by Apple, so on a standard Mac it opens without the unidentified-developer warning. Managed Macs may apply their own policies.From the folder containing the DMG, verify the exact artifact with shasum -a 256 "RPL Engine Workbench 1.0.0.dmg", hdiutil verify "RPL Engine Workbench 1.0.0.dmg", spctl -a -t open -vv "RPL Engine Workbench 1.0.0.dmg", and xcrun stapler validate "RPL Engine Workbench 1.0.0.dmg". After copying the app to Applications, verify it with codesign --verify --deep --strict --verbose=2 "/Applications/RPL Engine Workbench.app" and inspect the authority with codesign -dvvv "/Applications/RPL Engine Workbench.app".
The Apple notarization ticket is stapled to the distributed DMG. These checks verify file integrity, Developer ID signing, notarization, and code-signature consistency; they do not validate engineering accuracy.
To evaluate the results, follow the 15-minute evaluation: solve the built-in reference case and compare against the published LMAE reference project.

The trial is time-limited and feature-limited (watermarked PDF, no DXF/VTK export, reduced solve/mesh limits, one steady-state Flowfield solve per launch), and is the same on Windows and Mac. A purchased license unlocks the capabilities and limits of the chosen plan in the app you already installed. RPL Engine Workbench is preliminary engineering software; it does not replace qualified engineering judgment, testing, safety review, or export-control compliance. See the License FAQ.
