摘要
基于一种线红／黑排序法［１］．提出了解有限元方程组的一种并行解法。由于这种排序使得有限元刚度矩阵主对角线上的子块为三对角阵，故节省了计算机存贮，并通过并行求解降低了方程组的维数．减少了计算时间。
This paper describes a block paralled method for solving finite element equations based on the line red/black ordering.because the finite element coefficient matrix obtained is decomposited into a block matrix and all the diagonal blocks are tridiagonal submatrices.Therefore.the method save computer storages and the dimention of equations and computation time are reduced by parallel computation.
