Solidification of metals and alloys is a multi-physics phenomenon including thermal diffusion, solute diffusion, melt flow, solid motion, solid collision, grain growth and so on, and these have large influence on the solidification microstructure. On the other hand, there are no solidification simulations considering all of those phenomena particularly in the mesoscale considering dendrite morphology. In this study, we develop a multi-GPU parallel computational code for a phase-field lattice Boltzmann model which can express melt flow, motion and collision of dendrites, and following grain growth during solidification of a binary alloy. Using the developed code, we perform the two-dimensional large-scale phase-field simulations for the formation of equiaxed polycrystalline structure.
