Explicit Spectral Methods for Defense

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 defense, teams face challenges like blast and impact, signature management, reliability. The explicit spectral methods directly supports use cases such as ballistic fea, aerodynamics, electromagnetic modeling, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
