本文提出了一种半代数模式分析(SAMA),用于研究应用于二维和三维热方程有限元(FE)离散化的多重网格波形松弛方法的收敛性。与有限差分(FD)离散化相比,这种针对有限元方法的分析更为复杂且更具一般性,因为必须考虑质量矩阵。所提出的分析结果成为一种非常有用的工具,用于研究多重网格波形松弛方法随问题参数变化的行为。
英文摘要
In this work, a semialgebraic mode analysis (SAMA) is proposed for investigating the convergence of a multigrid waveform relaxation method applied to the Finite Element (FE) discretization of the heat equation in two and three dimensions. This analysis for finite element methods is more involved and more general than that for Finite Difference (FD) discretizations, since mass matrix must be considered. The proposed analysis results in a very useful tool to study the behaviour of the multigrid waveform relaxation method depending on the parameters of the problem.
