“…Solidification of alloys is a complicated multi-physics phenomenon including solid-liquid phase transformation, transport of solute and heat, liquid flow, solid motion, and solid deformation. PF modeling has been evolving from purely diffusive conditions to conditions with liquid flow [71], solid motion [72-76], and solid deformation [77,78]. As expected, the computational cost remarkably increases when additional phenomena are considered.…”

The current status of large-scale phase-field (PF) simulations for dendrite growth is reviewed by focusing on the study conducted by our group. The discussion includes the competitive growth of multiple columnar dendrites, dendrite growth with liquid flow and solid motion, permeability prediction, and cross-scale simulations using the PF method. All PF simulations introduced here were executed using a graphics processing unit (GPU) or a GPU supercomputer to significantly accelerate the PF simulations. Finally, the future perspectives of large-scale dendrite-growth PF simulations are discussed.

“…The phase field model has emerged as a powerful tool for numerical prediction of evolution processes in materials. It has been successfully applied to simulate the evolution of microstructures with complex morphologies in a wide variety of material processes such as, grain growth, [10][11][12][13][14][15] martensitic transformation, [16][17][18][19][20][21] solidification, [22][23][24][25][26][27][28] crack propagation problems, [29][30][31][32][33][34] ferrofluids, [35] and so on. The significant characteristic of phase-field methods is the diffuseness of the interface between two phases.…”

To understand the dielectric breakdown in a polycrystalline ferroelectric, a thorough phase field simulation has been performed by introducing a new degradation function. Time and position evolution of breakdown path, electric field dependence of breakdown time, and the effect of several parameters such as grain orientation, dielectric constant of grain and grain‐boundaries (GBs), thickness of GBs (dGB${d}_{\text{GB}}$), and grain size (Gnormala${G}_{\text{a}}$) on the threshold breakdown electric field, EBT${E}_{\text{BT}}$, are investigated. The results indicate that EBT${E}_{\text{BT}}$ is improved with decreasing dielectric constant. The dependence of EBT${E}_{\text{BT}}$ on grain size and GB's thickness obeys a power function Gnormala−n${G}_{\text{a}}^{-n}$ (n=0.42$n=0.42$) and dGBn${d}_{\text{GB}}^{n}$ (n=0.3$n=0.3$), respectively. The results help to engineer the grains and GBs properties and achieve a high breakdown electric field, which is very important in energy‐storage applications.
