heat-fvm

Simulate how heater positions, insulation, and climate affect heating costs.

A 2D finite-volume heat-flow simulator. Place windows, doors, and a heat source, pick a climate, and get a full year of heating simulated day by day — each day against ~86 years of ERA5 climate normals for that location. A reduced-order model makes the annual run take seconds instead of the half-hour the full solver would need.

This is a simplified theoretical model built for demonstration purposes. It has not been validated against real-world measurements — treat the numbers as illustrative, not predictive.
