Local and Parallel Finite Element Algorithms Based on Two-grid Discretizations for the Unsteady MHD Equations with Low Electromagnetic Reynolds Number

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Shi-lin mi Guang-zhi DU Yao RONG Li-yun ZUO School of Mathematics and Statistics Shandong Normal University College of Engineering Physics Shenzhen Technology University School of Mathematical Sciences University of Jinan

This paper mainly presents and studies some local and parallel finite element methods for the unsteady magnetohydrodynamic equations with low electromagnetic Reynolds number. Firstly, both the semi discrete and fully discrete local algorithms are provided and investigated, and the theoretical tool crucial to the analysis of the fully discrete local algorithm is obtained. Subsequently, we generalize the fully discrete local algorithm to the fully discrete parallel algorithm. At the end, some numerical experiments are provided to validate the effectiveness and efficiency of our algorithms.
