Ice Skating: Pressure Melting vs. Friction Heating (2D)

This is a simplified side-view cross-section of the same real dual-mechanism physics as the 3D version: a skate blade slides across an ice surface while the sim computes the tiny Clausius–Clapeyron pressure-melting depression and the much larger frictional flash-heating temperature rise side by side, showing which one actually creates the lubricating meltwater film at real skating speeds. Adjust skater mass, blade sharpness and contact length, skating speed, and ice temperature, drag the blade for a push, or drag the empty ice and scroll to pan and zoom the scene.
