THE APPLICATION OF MULTI-GRID METHOD IN THE CALCULATION OF SHALLOW-WATER WAVE
-
摘要: 本文给出了一种新的五对角系数矩阵的线性方程组的迭代方法,利用这个迭代方法,应用多重网格技巧建立了一种新的差分格式,并与HoPscotch技巧进行了比较。Abstract: In this paper, two finite-difference methods for shallow-water equation in absolute coordinate-system are proposed, an iterative algorithm is given, then the algorithm is applied to multi-grid methoe.
