摘要
展现了mortar型旋转Q1元的瀑布型多重网格方法.证明了采用共轭梯度作为光滑子的瀑布型多重网格法是最优的,而采用其它传统迭代作光滑子的瀑布型多重网格法是拟最优的.并通过数值试验验证了我们的理论结果.
In this paper, the cascadic multigrid method for mortar-type rotated Q1 element is discussed. It is proved that the cascadic conjugate gradinet method is optimal and the cascadic multigrid method with traditional iteration is nearly optimal. Numerical results confirm our theoretical analysis.
