SUMMARY:ISAV21:  Invited Speaker –3D CFD In-Situ Co-Processing for Turboma
 chinery Design
DESCRIPTION:Workshop\n\nISAV21:  Invited Speaker –3D CFD In-Situ Co-Proces
 sing for Turbomachinery Design\n\nGerstenberger\n\nReplacing gas turbine e
 ngine and rig tests with virtual simulation-based testing requires more ac
 curate physical and mathematical models as well as more detailed geometry 
 and realistic boundary conditions. However, the improved accuracy is achie
 ved at the cost of ever increasing demands on the HPC systems.  Among othe
 rs, IO bandwidth for reading and writing solver results to disk and the sp
 ace it takes to store those results are major limitations for our current 
 simulation needs. As a remedy, in-situ co-processing has been identified a
 s a key ingredient to overcome those IO difficulties, which not only saves
  time, but enables new simulation areas that were simply not possible on l
 imited HPC resources before.\n\nThis presentation gives an overview on whe
 re co-processing is needed within Rolls-Royce. It then illustrates how sev
 eral in-situ approaches, in particular Catalyst, Libsim, Sensei, and Score
 Board/Kombyne, were assessed and implemented within the LuFo project PREST
 IGE. For illustration, a number of example simulations demonstrate the use
 fulness of in-situ capabilities for Rolls-Royce CFD applications. Finally,
  future steps are outlined to further improve on this initial implementati
 on.\n\nTag: Applications, Big Data, Visualization\n\nRegistration Category
