🌡️ Heat Equation Simulator (2D)

2D Canvas simulation of the heat equation dT/dt = a * Laplacian(T), solved with an explicit finite-difference scheme on a 120x120 grid. Click or drag to place heat sources, tune the thermal diffusivity, and switch between fixed and insulated boundaries while a live HUD tracks peak temperature, total thermal energy and elapsed time.
