Multiple-GPU Scalability of Phase-Field Simulation for Dendritic Solidification
Mechanical properties of metallic materials like steel depend on the solidification process. In order to study the morphology of the microstructure in the materials, the phase-field model derived from the non-equilibrium statistical physics is applied and the interface dynamics is solved by GPU computing. Since very high performance is required, 3-dimensional simulations have not been carried o...
متن کاملPhase-field Simulation of Dendritic Solidification
We consider the solidi cation of a pure material from its undercooled melt, taking into account e ects of surface tension, kinetic undercooling and crystalline anisotropy. The classical mathematical formulation consists of two heat equations coupled with boundary conditions prescribed at the moving solid-liquid interface. Analytic solutions are known only for a few special cases. Since the prob...
متن کاملTime-stepping schemes for phase-field simulation of dendritic solidification
Two di erent time-stepping schemes are investigated for a phaseeld model of solidi cation of a pure material. A rst order accurate semiexplicit scheme which is computationally cheap per time step is compared to a more accurate fully implicit BDF-discretization. The implementation of fast Poisson and Newton-GMRES solvers are discussed in some detail. Convergence rates are experimentally validate...

متن کاملParallel Implementation for Phase-Field Simulation of Flow Effect on Dendritic Growth with GPU Acceleration
A Sola-phase field model combined Sola algorithm with phase-field model is established. It is difficult to implement real-time simulation as the computational grids increase. Taking pure SCN for example, the solidification microstructure evolution process in the presence of flow has been accelerated on a GPU with CUDA programming. The GPU implementation of the Sola-phase field model is introduc...
