2D Semi-Implicit Euler for Water & Wastewater

This is the 2d 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 water & wastewater, teams face challenges like flow assurance, mixing and aeration, contaminant transport. The 2d semi-implicit euler directly supports use cases such as pipe-network hydraulics, aeration mixing, contaminant dispersion, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
