GPU-accelerated phase field simulation of directional solidification

The phase field simulation has been actively studied as a powerful method to investigate the microstructural evolution during the solidification. However, it is a great challenge to perform the phase field simulation in large length and time scale. The developed graphics processing unit (GPU) calculation is used in the phase filed simulation, greatly accelerating the calculation efficiency. The results show that the computation with GPU is about 36 times faster than that with a single Central Processing Unit (CPU) core. It provides the feasibility of the GPU-accelerated phase field simulation on a desktop computer. The GPU-accelerated strategy will bring a new opportunity to the application of phase field simulation.
