Abstract: Replacing gas turbine engine and rig tests with virtual simulation-based testing requires more accurate physical and mathematical models as well as more detailed geometry and realistic boundary conditions. However, the improved accuracy is achieved at the cost of ever increasing demands on the HPC systems. Among others, IO bandwidth for reading and writing solver results to disk and the space it takes to store those results are major limitations for our current simulation needs. As a remedy, in-situ co-processing has been identified as a key ingredient to overcome those IO difficulties, which not only saves time, but enables new simulation areas that were simply not possible on limited HPC resources before.
This presentation gives an overview on where co-processing is needed within Rolls-Royce. It then illustrates how several in-situ approaches, in particular Catalyst, Libsim, Sensei, and ScoreBoard/Kombyne, were assessed and implemented within the LuFo project PRESTIGE. For illustration, a number of example simulations demonstrate the usefulness of in-situ capabilities for Rolls-Royce CFD applications. Finally, future steps are outlined to further improve on this initial implementation.
