Explicit Smoothed-Particle Hydrodynamics (SPH) for Rail & Transit
Apply the explicit smoothed-particle hydrodynamics (sph) to real rail & transit problems — in the browser, with AI assistance.
This is the explicit variant of the Smoothed-Particle Hydrodynamics (SPH). SPH represents a fluid as particles carrying properties smoothed by a kernel, excelling at free-surface and splashing flows without a grid.
In rail & transit, teams face challenges like aerodynamics, track loading, braking thermal. The explicit smoothed-particle hydrodynamics (sph) 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
