  • 508 Adaptive Phase-Field Simulation during Grain Growth

抄録

Efficient adaptive finite element technique, in which fine meshes are restricted around the grain boundaries, is applied to phase-field simulation of grain growth. The computing speeds for each step are improved with progress of simulation, because the number of finite elements is reduced with increasing of time steps due to the reduction of area for grain boundaries which is induced by the grain rotation and the movement of grain boundary.
