We report the results of a two-dimensional reference model for the formation of facets on the left and right side of a silicon monograin that is solidified by pulling a thin sample in a constant temperature gradient. Anisotropy functions of both the

Three-dimensional phase-field simulations are performed to follow the formation of facets at the surface of a silicon crystal in contact with its melt. We focus on the anisotropies of both the surface energy and the kinetic attachment coefficient. An
