Implicit Semi-Implicit Euler for Packaging

This is the implicit 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 packaging, teams face challenges like drop protection, material cost, sustainability. The implicit semi-implicit euler directly supports use cases such as drop-test fea, cushioning analysis, material optimization, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
