摘要:In this talk we analyze and implement a second-order-in-time numerical scheme for the three-dimensional phase field crystal (PFC) equation. We present a detailed convergence analysis in this article, in which the maximum norm estimate of the numerical solution over grid points plays an essential role, which is proved by discrete Fourier Transformation combined withe energy identity. Moreover, we outline the detailed multigrid method to solve the highly nonlinear numerical scheme over a cubic domain, and various three-dimensional numerical results are presented, including the numerical convergence test, complexity test of the multigrid solver and the polycrystal growth simulation.
