题目:Towards the efficient and robust numerical methods for Kohn-Sham equation
摘要:In this talk, we will introduce our recent work on the adaptive finite element framework for Kohn-Sham density functional theory. The background of Kohn-Sham DFT, as well as the challenges in developing robust and efficient numerical methods will be briefly described. In our work, an h-adaptive finite element framework has been proposing, and several numerical techniques such as the algebraic multigrid method, imaginary time propagation preconditioning, and multilevel correction, has been successfully applied on the algorithm towards the efficiency and robustness. A variety of numerical experiments will be demonstrated to show the effectiveness of our method.
