Abstract
We present a cellular automata model for computing the grain evolution during directional solidification of silicon on a meso-scopic scale. Firstly, the method is applied to test cases with different shapes of the melt/crystal interface. In a second step we compute the case of an experiment with in-situ observation of the interface shape evolution (Tandjaoui et al., 2012). Here we also include the effect of twinning. The interchanging appearance of two twins could be revisited by our calculations. The probabilities used correspond to those which were analytically derived for an undercooling of ΔT=0.6K (Lin and Lan, 2017). This undercooling is a typical value for a groove with 〈111〉 facets (Miller and Popescu, 2017).
