Abstract Cellular automaton (CA) was used in simulating the microstructure evolution during solidification, and finite difference method (FDM) was used in solving the conservation equations for heat transfer, solute transfer and momentum transfer which govern the macro--transport phenomena during solidification. Coupling of CA with FDM (CA--FDM) could predict the microstructure evolution under varied solidification conditions, including the length of the columnar grains and the columnar-to-equiaxed transition (CET). It was found that the ratio of nucleation rate and growth rate is essential to the morphology formation and CET. To maximize the number of the simulated cells, the virtual memory allocation technique was adopted.

Key words: cellular automaton solidification microstructure macro--transport model
