摘要
网格加密型高效算法包括多重网格法、自适应局部加密算法、外推算法等.它们是在有限元法(或差分法)基础上,借助于网格加密技术发展起来的高效算法.这些算法在理论上已基本成熟,其效率明显高于一般有限元算法.
The efficient algorithms with grid refinement consist of multi-grid, adaptive grid refi-nement, extrapolation and so on. Based on the research on the efficient algorithms with gridrefinement, a nested data structure is given. The storage can be decreased to 39.6%, and the effi-cency increased to 5.33 time with the nested data structure. The efficiency of algebraicoperations can be raised when the nested dissection is used.
