Transient Turbulence Modeling (RANS/LES) for HVAC & Buildings

Apply the transient turbulence modeling (rans/les) to real hvac & buildings problems — in the browser, with AI assistance.

This is the transient variant of the Turbulence Modeling (RANS/LES). RANS averages the flow and models turbulence, while LES resolves large eddies and models the small ones — trading cost for fidelity.

In hvac & buildings, teams face challenges like thermal comfort, energy efficiency, air quality. The transient turbulence modeling (rans/les) 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.
