摘　　要：为有效解决规模庞大的数值计算问题,充分利用机器资源,提高计算效率,基于线性元有限体积格式,通过区域分解法,在三角形网格上提出一种适用于在多核机器或并行系统上运算的并行格式.数值实验结果表明,该格式在各类扭曲网格上,不仅可达到最佳的收敛速度,而且拥有良好的并行效率.In order to effectively solve large-scale numerical calculation problems, make full use of machine resources and improve computational efficiency, based on the linear element finite volume scheme, we proposed a parallel scheme suitable for computing on multi-core machines or parallel systems on triangular meshes by domain decomposition method. The results of numerical experiments show that the scheme can not only achieve the best convergence speed, but also have good parallel efficiency on various distorted meshes.
