Explicit Semi-Implicit Euler for Automotive

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 automotive, teams face challenges like drag and fuel economy, crash safety, battery thermal management. The explicit semi-implicit euler directly supports use cases such as external aerodynamics, crashworthiness fea, ev battery cooling, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
