🌋 2D Magma Intrusion Cooling: Dike and Sill Solidification, Contact Aureole and the Jaeger Solution

A one-dimensional enthalpy model of a hot dike or sill cooling in cold country rock: latent heat of crystallisation, contact temperature, freezing time, peak-temperature baked zones and thermocouple traces, checked in the page against the closed-form Jaeger (erf) solution.
