The anisotropic kinetic function, i.e., Eq. (6), for different d
values is shown in Fig. 4(a), which indicates a peak value at 451;
the peak value gives b 11 ¼5.1 s/m (n¼10). The larger d value gives
a narrower distribution. The evolution of the interface morphol-
ogies ( f ¼0) based on d ¼4, 16, and 64 are, respectively, shown in
Fig. 4(b), (c) and (d) for n¼10 and e 4 ¼0.25. Small perturbations
(40 small waves) are introduced at the beginning. The interval
for each interface is 0.22 s and the total elapsed time is 3.3 s.
In general, as shown in all cases, big facets develop within
1 s, by consuming the small ones. This is consistent with the experimental observations [2]. Unfortunately, the step merging is
not through the step growth as observed in the experiment
