Abstract
Calculations of flows with combustion in complex geometries impose high computational demands. This applies in particular to highly transitional flow, where accuracy requirements cause long computation time. Parallelization in space and time, based on domain decomposition techniques is applied and reduction on turn-around time is documented. On networked computers, large applications — beyond present single processor workstation capacity — can thus be solved. The approach presented has been implemented and benchmarked on different platforms. Using encapsulated message passing routines based on PVM and MPI libraries, it is possible to port the code on different hardware platforms ranging from workstation clusters up to massively parallel computers. For two examples, results are presented and performance issues are discussed.
