Explicit Semi-Implicit Euler for Defense

This is the explicit variant of the Semi-Implicit Euler. Semi-implicit (symplectic) Euler updates velocity before position, conserving energy well over long runs — the default for real-time particle and rigid-body physics.

In defense, teams face challenges like blast and impact, signature management, reliability. The explicit semi-implicit euler 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.
