Two-dimensional square mesh for computation. The thick solid curve is the actual surface of droplet. The computational cells inside (white) and outside (gray) the actual surface are defined by whether positions of their centers locate the inside or outside, respectively. The computational surface (thick dashed lines) is the mesh boundaries between inside cells and outside cells. The crystal growth is triggered by a seed crystal at the droplet surface.
