The linear systems used for performance benchmarks athttps://github.com/ddemidov/cppstokes_benchmarks. The files correspond to the Stokes equation discretized for 3 different cases: Unit cube problem (ucube). Arotating flow driven by an external force f in a closed unit cube. Converging-diverging tube problem (cdtube). Pressure-driven tube flow through a 3D converging-diverging tube under a pressure drop of 1Pa. Sphere packing problem (spack). Acomplex sphere packing flow problem withnon-uniform cell size distribution and large cell size contrast. Each problem contains the system matrix (A.bin), the RHS vector (b.bin), and the text file containing the number of DOFs corresponding to the velocity field (u.txt) for 6 to 7 different problem sizes.
