A phase field model for snow crystal growth in three dimensions

Spontaneous patterns: Simulating snowflakes with a softer touch A model that reproduces complex 3D snowflake growth using versatile interface descriptors may benefit other dendritic materials. Snow crystals solidify by expanding outward from an initial seed, capturing water molecules as they travel...
