报告简介：

The Landau-Lifshitz-Gilbert equation is an important governing equation in computational micromagnetics. Its efficient solver is crucial in finding ground state and resolving the dynamics of the magnetisation in a given magnet, which further has wide applications in designing next generation storage device, etc. In this talk, a framework of numerical solutions of Landau-Lifshitz-Gilbert equation, consisting of a structure preserving temporal discretisation and a finite element spatial discretisation, is introduced. Several numerical issues towards developing an O(N) algorithm are discussed in detail. The numerical performance of our algorithm is demonstrated by several experiments, following by the recent progress in this work.
