Explicit Spectral Methods for Rail & Transit

This is the explicit variant of the Spectral Methods. Spectral methods expand the solution in Fourier or Chebyshev modes for exponential accuracy on smooth problems.

In rail & transit, teams face challenges like aerodynamics, track loading, braking thermal. The explicit spectral 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.
