Acceleration of phase-field dendrite growth simulation by GPU implementation of AMR

Abstract

In this study, the adaptive mesh refinement (AMR) method is applied to a phase-field dendrite growth simulation using a graphic processing unit (GPU). To evaluate a computational efficiency of the implemented AMR method, dendrite growth simulations during directional solidification with and without AMR are performed. From simulation results, we confirmed that a good computational acceleration is achieved by the introduction of AMR.
