Nothing leaves your machine
The tools execute entirely in your browser via WebAssembly. Altrusion runs no simulation servers and never sees your inputs. For defense, nuclear, and export-sensitive work, that's not a feature. It's the requirement.
Unlimited · 98 in-browser tools · Beta
Engineering answers in your browser, with honest error bars.
Design Studio puts 98 validated engineering design tools in the Altrusion portal: plasma power balances to bolted-joint margins to dilution-fridge heat loads. Everything runs client-side in your browser: your geometry, loads, and operating points never leave your machine. And every answer ships with a bounded uncertainty interval, not false precision.
Why it's different
Built for programs that can't upload their designs.
Bounded results, not false precision
Skip the inputs you don't know yet. The answer honestly widens to cover them, and the report names exactly which input to pin down to tighten it. Physically scattering quantities like friction and emissivity stay uncertain even when you set them, because in reality they are.
Anchored, not hand-waved
Every model is tested against published handbook values and exact closed-form identities, with hundreds of validation anchors across the catalog. Every transcribed constant and fitted curve is flagged in the report. Level 1: indicative, and labeled that way.
Bounded results
Start with what you know. The tool covers the rest.
01
Enter the key inputs
Each tool asks for the handful of numbers that define your problem: the load, the pressure, the geometry. Everything else is optional refinement.
02
Skip what you don't know
Optional inputs you leave at their defaults carry declared uncertainty bands. The tool propagates them through the physics: Monte Carlo, not guesswork.
03
Get an interval and a next step
Results lead with a 90% interval around the nominal answer and tell you which missing input drives the spread, so your next measurement is the one that matters.

98 tools across eight verticals.
Grouped the way the in-app picker groups them. Many tools serve more than one vertical, so they appear wherever you'd look for them.
