报告摘要：
In this talk, our recent progress towards developing O(N) algorithms for solving Landau-Lifshitz-Gilbert equation, which is a fundamental equation in computational micromagnetics, will be reported. In the first part of this talk, the work in [Yang, Chen, H, J. Comput. Phys.,2021] will be reviewed, in which the bottleneck of the efficiency, i.e., the calculation of the demagnetization, will be introduced. In the second part, an O(N) algorithm consisting of a combination of PDE approach and treecode algorithm will be described in detail. The implementation based on the software AFEMAG will also be demonstrated. The performance of this algorithm will be demonstrated by numerical examples.
