Grains structures obtained during solidification processes strongly influence the properties of technical products. It is specially the case for cast parts in metallic alloys, or for silicon photovoltaic cells. The CA-FE (Cellular Automaton - Finite Elements) method aims to model grain structure evolution during solidification at a macroscopic scale, but also requires approximations at smaller scales. In this work, two distinct studies are proposed. First, CA simulations of growth competition among columnar dendritic grains are carried out for a succinonitrile-0.4 wt% acetone alloy. This is achieved by computing the grain goundary orientation during directional solidification. Comparisons are subsequently conducted with recent phase field r...
