Abstract:In this talk, the background and recent development of numerical methods for density functional theory will be briefly reviewed first. Then focusing on efficiency of simulations, several numerical issues such as convergence of SCF iteration, adaptive mesh methods, orthonormalization constraint for wavefunctions, parallel computing, will be introduced. The solutions of above issues, within our h-adaptive finite element framework, will be described in detail. Numerical experiments show the effectiveness, as well as some potential issues of our method.
