Navier-Stokes Problem For Shared Memory Amgcl Benchmarks

The system matrix and the right hand side used in the shared memory Navier-Stokes benchmark at https://github.com/ddemidov/amgcl_benchmarks. This is an incompressible Navier-Stokes problem discretized on a non uniform 3D mesh with a finite element method. The overall system matrix for the problem was assembled in the [Kratos](http://www.cimne.com/kratos/) multi-physics package developed in CIMNE, Barcelona. The matrix has block structure with blocks of 4-by-4 elements, and contains 713'456 unknowns and 41'277'920 nonzeros.本数据集包含https://github.com/ddemidov/amgcl_benchmarks 中的共享内存纳维-斯托克斯（Navier-Stokes）基准测试所使用的系统矩阵与右端项。 该问题为不可压缩纳维-斯托克斯问题，采用有限元法在非均匀三维网格上离散得到。问题的整体系统矩阵由巴塞罗那国际工程数值方法中心（CIMNE）开发的Kratos多物理场软件包完成组装。该矩阵采用4×4单元块的分块结构，包含713456个未知量与41277920个非零元素。
