摘要
为了增加一维压缩存储求解法的适应性和通用性,提出了一种稀疏矩阵的拟一维压缩存储求解法.该方法是用多个相同大小的存储空间来替代单个的相当大的存储空间,同时存储顺序尽量与计算时的访问顺序相同.该方法用于充模流动分析时,获得了比较理想的计算效果.
In the paper, one compressed storing strategy of matrix was proposed to solve the flow problem of moving boundaries and was applied to mold filling simulation. Many fixed-size memory spaces are allocated to store sparse matrix; the storing strategy are designed to match the order of the solver. The control volume finite element is used in the numerical simulation. Case studies showed that the proposal strategy enhances the flexibility of one-dimensional compressed storing approach and is effective for mold filling simulation.
