Vertical 2 is live: external aerodynamics of a motorbike, developed together with Aprilia. 🏍️
The model predicts surface pressure and wall shear stress over the full vehicle, and integrates them into drag and lift coefficients — the numbers an aerodynamicist actually decides on. Accuracy against the reference CFD is within 2% on the average fields and 1% on the integral quantities, which is the range where a surrogate stops being an approximation you check and starts being a result you work from.
Geometry can come from the parametric design library, from a generative model that produces entirely new windshield shapes, or from an STL uploaded straight from CAD. That last point is what makes it useful in practice: a designer can bring their own geometry, see its aerodynamic behaviour immediately, and iterate within a single session rather than across a week of simulation runs.
Vertical 2 is available now on the Spaider-AI platform.
