In-Situ Solver Integration using VisIt on the CREATE/AV Program

Helicopter and CarrierDoD's CREATE/AV Kestrel team has demonstrated in-situ post-processing using DOE's VisIt code with FieldView XDB export.

The US Air Force, Navy and Army make extensive use of large scale simulation in their research, design and procurement activities.  Over the past five years the DoD CREATE program has sought to develop and deploy new simulation technologies to assist in the procurement process.

As part of a ship-airwake program, engineers at the US Navy’s NAVAIR were tasked with simulating a helicopter flying towards a ship. This was a particularly challenging case due to the sheer size of the results files computed on an HPC resource.  Handling the files was an impediment to effective understanding.  With support from Intelligent Light's VisIt Services, the team now has the ability to use their solver with open-source VisIt LibSim software module to perform in-situ post-processing and export XDB files.

Intelligent Light also provided support and enhanced VisIt to make it suitable for the complex mesh topologies common in Kestrel. The VisIt 2.8.0 release has many of these enhancements and the XDB export capability.

Intelligent Light VisIt Services delivered:

  • Rapid deployment of solutions to the problems identified by an expert VisIt developer
  • In-situ extraction via VisIt solves the problems with moving huge files in unsteady computation
  • XDB export in VisIt provides persistent extracts that can be further post-processed and visualized in FieldView
  • Services & support provided by a trusted vendor partner
