摘要
研究了一种mortar型旋转Q1元的多重网格方法,证明了W循环多重网格算法的最优收敛性,即收敛率与网格层数和尺寸无关,数值仿真验证了理论分析.
In this paper,we study a multigrid method for a kind of mortar-type rotated Q1 element.It is proved that the convergence of the W-cycle multigrid is optimal,i.e.,the convergence rate is independent of the grid levels and size.Numerical experiments are presented to confirm our theoretical results.
