Jacobi / Gauss–Seidel Iteration for Rail & Transit
Apply the jacobi / gauss–seidel iteration to real rail & transit problems — in the browser, with AI assistance.
These stationary iterative methods relax toward the solution of Ax=b, used inside pressure projection and diffusion steps of fluid and thermal solvers.
In rail & transit, teams face challenges like aerodynamics, track loading, braking thermal. The jacobi / gauss–seidel iteration 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
- Rail structural FEA
- Brake thermal analysis
