Domain Decomposition Methods and Adaptive Flow Simulation on Unstructured Meshes
S. Bikker, Wolfgang W. Koschel · 1995
A Taylor-Galerkin finite dement scheine to solve the compressible Navier-Stokes equations on completely unstructured triangular (2D) or tetrahedral (3D) meshes has been implemented on a MIMD parallel machine. Within the paper three different approaches concerning domain decomposition methods for distributing the work to the processors envolved will be discussed. In order to improve the solution accuracy, special mesh adaptation techniques such as h-enrichment and mesh movement are used. Speed-ups are taken and comparisons are made between Parsytec SC256, IBM3090 and Siemens S600 to investigate the computational power and the efficiency of the implementation.
