3D Semi-Lagrangian Advection for Rail & Transit
Apply the 3d semi-lagrangian advection to real rail & transit problems — in the browser, with AI assistance.
This is the 3d 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 rail & transit, teams face challenges like aerodynamics, track loading, braking thermal. The 3d semi-lagrangian advection directly supports use cases such as train aerodynamics, rail structural fea, brake thermal analysis, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.

- Train aerodynamics
- Rail structural FEA
