Explicit Finite Difference Method (FDM) for HVAC & Buildings

Apply the explicit finite difference method (fdm) to real hvac & buildings problems — in the browser, with AI assistance.

This is the explicit variant of the Finite Difference Method (FDM). FDM replaces derivatives with difference quotients on a regular grid — simple to implement and ideal for diffusion, wave, and reaction–diffusion PDEs.

In hvac & buildings, teams face challenges like thermal comfort, energy efficiency, air quality. The explicit finite difference method (fdm) 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.
