Abstract
In recent crystal growth experiments [J. Maurer et al., Europhys. Lett. 8, 67 (1989)], faceted dendrites have been observed. These new diffusion-limited growing shapes have been described theoretically by means of the classical equations of dendritic growth and by using modified boundary conditions on the faceted parts of the interface. We propose a numerical treatment of the present set of equations in the limit of low undercooling. Steady faceted needle crystals are found with a growth rate selected by the amplitude of the cusp in a Wulff plot.Keywords
