🧪 Coal Stockpile Self-Heating & Thermal Runaway (2D)

2D reaction-diffusion lab for coal-stockpile spontaneous combustion: an Arrhenius heat-generation term competes with 2D heat diffusion and convective surface cooling, so you can push pile height, ambient temperature, coal reactivity and ventilation past the point where core heating runs away toward ignition.

This 2D companion strips the pile down to a cross-section heatmap driven by the same coupled physics as the 3D scene: an Arrhenius heat-generation term at every grid cell competes against 2D conductive diffusion through the coal and convective cooling at the exposed surface. A live history graph tracks the hottest cell in the pile against a marked ignition threshold, so raising pile height, ambient temperature or coal reactivity — or cutting ventilation — visibly tips the same equations from a stable warm steady state into an accelerating thermal runaway, the real mechanism behind stockpile spontaneous-combustion incidents.
