摘要
在采用Metis软件包进行区域分解的基础上,结合大型稀疏矩阵的行压缩存储方式,求解基于预处理共轭梯度法的有限元方程组,开发并行有限元计算程序。对三维地质模型进行计算模拟,得到的张店-仁河断裂近断层地震危害场的位移场数值计算结果表明,该并行程序取得了较好的计算加速比。
On the basis of Metis package to decompose domain, this paper combines with row compressed storage mode of large sparse matrix, develops the parallel finite element program according to preconditioned conjugate gradient method for solving finite element equations. Through the calculational simulation to the 3D geological model established, the displacement field simulation result of Zhangdian-Renhe near-fault endangered field indicates that the procedure has a good parallel speedup.
