Explicit Semi-Lagrangian Advection for Water & Wastewater

This is the explicit variant of the Semi-Lagrangian Advection. Semi-Lagrangian schemes trace characteristics backward in time and interpolate, giving stability at large timesteps — the basis of Stam's Stable Fluids.

In water & wastewater, teams face challenges like flow assurance, mixing and aeration, contaminant transport. The explicit semi-lagrangian advection 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.
