| Abstract | A parallel automated adaptive methodology for the analysis of steady and unsteady compressible fluid flows on distributed memory computers is presented. The technique developed here relies on a stabilized implicit space-time finite element formulation, on a domain decomposition based strategy for achieving parallelism while efficiently exploiting data locality, on an edge based adaptive scheme that combines refinement, derefinement and triangulation optimization. An element migration and load balancing procedure is used for reducing the load imbalance caused by the adaptation process. The message passing paradigm is employed in each stage of the analysis, realizing a uniform software environment that shares a common data structure. Some preliminary results relative to the parallel adaptive analysis of compressible flow problems are presented at the end of the paper. |
