Documentation
AviatoStudio runs engineering simulation — fluid flow, structural mechanics, heat — from your browser, priced per run. Three ideas shape everything here:
- A run that succeeds did what you asked. If a setting can't be honoured, the run refuses up front and says why — it never silently substitutes something else.
- Claims are benchmarked. Anything marked Validated has a closed-form comparison behind it that you can read — including the ones that miss — on the Validation page.
- Units travel with numbers. Type a modulus in GPa or a PSD in g²/Hz; conversion happens once, at the door, and implausible values are refused before a machine is billed.
Every analysis, material model, support, load and output — rendered live from the catalog the solver itself runs on, with units, plain-language help and validation status.
The benchmark record: each claim against its closed form or published reference, with the measured deviation — including the entries that are not yet green.
Tutorials
Open Quick run and pick a geometry — the sample library's cantilever beam is the validated reference part, or upload your own CAD/mesh.
Choose Structural → Strength → Stress & deflection. Each named face of the mesh appears with a condition dropdown: clamp one face (Fixed support), load another (Force, in newtons — the platform divides by the face area for you).
Pick a material from the library (each entry cites its source) and launch. The price is shown before you commit; a typical run costs cents.
The result page gives peak deflection, von Mises stress and a safety factor, with the 3-D field live while it solves. A part that is free to fly away is refused, not "solved".
Find the resonances: run Natural frequencies first. Everything else in a qual campaign is about where these sit.
Shaker sine sweep: in Response to a shaking force, set the drive to base, give the base acceleration from the test spec (usually in g) and sweep through the first mode. The reported motion is relative to the base — the motion that stresses the part.
Shock spectrum: paste the qualification standard's (frequency, acceleration) table straight into the spectrum analysis — two-column paste from a spreadsheet works.
Random vibration: paste the g²/Hz PSD table the same way. You get the RMS response (1σ); rare peaks reach about 3× it.
Hours to failure: enable the fatigue output on the PSD run, name the face to count damage at (a weld, a support) and give your S-N curve. The answer is service hours of that vibration environment — the number a qual report actually signs.
Pick a turbulence treatment under Fluid flow: k-ω SST is the engineering default; Laminar is the honest choice for low-Reynolds internal flow and natural convection (validated against the heated-cavity benchmark).
Give any wall a temperature or a heat flux and the temperature solve turns on by itself — walls you leave blank stay adiabatic. The inlet stream temperature lives on the inlet.
For buoyancy (hot air rising), set the expansion coefficient β and gravity in the fluid properties — density then follows temperature and the flow drives itself.
A filter or radiator inside the domain is a porous zone: name the volume region in your mesh and set its head-loss coefficient instead of meshing a thousand holes. The pressure drop is validated against the closed form.
Every field in the forms carries its own in-context help (the ⓘ marks) — this page is the map, those are the territory. If something you need is missing, the capability reference lists what is planned and what was deliberately declined, each with the reason.
