The mechanical properties of metal materials largely depend on their intrinsic internal microstructures. To develop engineering with the expected properties, predicting patterns in solidified metals would be indispensable. phase-field simulation is most powerful method known to simulate micro-scale dendritic growth during solidification a binary alloy. evaluate realistic description solidification, however, requires computing large number complex nonlinear terms over fine-grained grid. Due...
Regional weather forecasting demands fast simulation over fine-grained grids, resulting in extremely memory- bottlenecked computation, a difficult problem on conventional supercomputers. Early work accelerating mainstream code WRF using GPUs with their high memory performance, however, resulted only minor speedup due to partial GPU porting of the huge code. Our full CUDA high- resolution prediction model ASUCA is first such one we know date; next-generation, production developed by Japan...
Abstract Grain growth, a competitive growth of crystal grains accompanied by curvature-driven boundary migration, is one the most fundamental phenomena in context metallurgy and other scientific disciplines. However, true picture grain still controversial, even for simplest (or ‘ideal’) case. This problem can be addressed only large-scale numerical simulation. Here, we analyze ideal via ultra-large-scale phase-field simulations on supercomputer elucidating corresponding authentic statistical...
Primary arm arrays formed during the directional solidification of a single-crystal binary alloy were investigated by performing large-scale phase-field simulations using GPU supercomputer TSUBAME2.5 at Tokyo Institute Technology. The primary array and spacing Voronoi decomposition Delaunay triangulation, respectively. It was concluded that hexagonal dominant for both dendrite cell structures penta–hepta defects, which are typical defects in patterns, formed. arms continuously moved such...
To realize human induced pluripotent stem cell (hiPSC)-based cardiac regenerative therapy, evidence of therapeutic advantages in human-sized diseased hearts are indispensable. In combination with an efficient and simultaneous differentiation various lineages from hiPSCs sheet technology, we aimed to generate clinical-sized large tissue sheets (L-CTSs) evaluate the potential porcine infarct heart. We simultaneously cardiomyocytes (CMs) vascular cells [vascular endothelial (ECs) mural (MCs)]...
Competitive grain growth during the directional solidification of a polycrystalline binary alloy is investigated by performing systematic three-dimensional large-scale phase-field simulations with GPU supercomputer TSUBAME2.5 at Tokyo Institute Technology. Contrary to two-dimensional investigations, in which an unusual unfavorably oriented (UO) grains has been observed frequently preference favorably (FO) ones, selection present follows essentially Walton and Chalmers model, FO are...
Abstract In the phase-field simulation of dendrite growth during solidification an alloy, computational cost becomes extremely high when diffusion length is significantly larger than curvature radius a tip. such cases, adaptive mesh refinement (AMR) method effective for improving performance. this study, we perform three-dimensional in which AMR implemented via parallel computing using multiple graphics processing units (GPUs), provide computation GPU computation, apply dynamic load...
