Dendrites are the tree-like microstructures that form during solidification. They form when molten metal or alloy freezes from liquid state, which may happen during many industrial manufacturing processes. The morphology, size, and spacing between dendritic arms have a significant influence on material properties.

We developed a numerical model based on lattice Boltzmann LB and cellular automaton CA methods to simulate dendrite growth in 3D. The low computational cost and great scalability of the LB-CA model enabled us to perform large-scale 3D simulations in macro size domains. It is known that melt flow can significantly alter the dendrite growth kinetics by affecting solutal gradient around the dendrites.
