Multigrid Methods for Rail & Transit
Apply the multigrid methods to real rail & transit problems — in the browser, with AI assistance.
Multigrid solves error components on a hierarchy of grids, achieving near-optimal convergence for elliptic problems.
In rail & transit, teams face challenges like aerodynamics, track loading, braking thermal. The multigrid methods 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.
Typical Rail & Transit use cases
- Train aerodynamics
