Steady-State Semi-Lagrangian Advection for Sports & Wearables

Apply the steady-state semi-lagrangian advection to real sports & wearables problems — in the browser, with AI assistance.

This is the steady-state variant of the Semi-Lagrangian Advection. Semi-Lagrangian schemes trace characteristics backward in time and interpolate, giving stability at large timesteps — the basis of Stam's Stable Fluids.

In sports & wearables, teams face challenges like aerodynamics, comfort and fit, battery life. The steady-state semi-lagrangian advection directly supports use cases such as cycling aerodynamics, fabric drape, wearable thermal design, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
