Semi-Lagrangian Advection for HVAC & Buildings

Apply the semi-lagrangian advection to real hvac & buildings problems — in the browser, with AI assistance.

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

In hvac & buildings, teams face challenges like thermal comfort, energy efficiency, air quality. The semi-lagrangian advection directly supports use cases such as room airflow cfd, building energy modeling, duct design, and PolySim's AI Copilot can recommend settings and catch common setup errors before you run.
