1. Simulation of Snow Metamorphism Pedro Rodriguez

2. Method  Part 1: Constructing a snowpack  Bi-continuous Model: summation of randomized cosine vectors + cutoff  Part 2: Mass Transfer by Temperature Gradient  Fick Flow drives mass transfer  In simulation, empirical mass transfer used  Particles sublimated, then deposited  Run ‘main.m’
