With a goal of improved pilot training for Sea-based aircraft operations, the CREATE™–AV team took on the task of coupling CREATE–AV Kestrel to the Navy flight simulator CASTLE. This two-way coupling might lead to better simulation of a difficult landing environment.
The high temporal fidelity of 45 seconds at 60 files per second meant that an innovative approach would be needed to handle the data. The CREATE™–AV team reached out to Intelligent Light for help.
I hope you will join me for this live event.

Accelerating the Post‐Processing of Large Scale Unsteady CFD Applications via In Situ Data Reduction and Extracts
Dr. Earl P.N. Duque
Manager of Applied Research, Intelligent Light
Tuesday, April 14th, 2015
Lehman Building Room 272
Writing, storing, moving and post‐processing vast unsteady datasets can interfere with an engineer’s interpretation and reporting of results. This seminar will present ongoing research to develop new methods designed to extract and reduce large unsteady CFD derived volumetric data. In‐Situ data extraction whereby sub‐setting and segmenting the volume data using data extraction and analysis libraries directly integrated within the solver codes themselves is the first step. To further reduce the amount of unsteady CFD extract data written to disk, methods such as Proper Orthogonal Decomposition may be used to reconstructed the solution data within a given error band. This seminar will present preliminary research and how the CFD could use these techniques to analyze their large‐scale CFD solutions.
BIO: Dr. Duque manages the Applied Research Group at Intelligent Light, the makers of the leading CFD post‐processing software FieldView. Previous to Intelligent Light, he was a tenured Professor of Mechanical Engineering at Northern Arizona University. Prior to his time at the university, he was a Research Scientist for the Army’s Rotorcraft CFD Applications Group located at the Numerical Aerodynamic Simulation Facility at NASA Ames Research Center. His current research focuses upon the development of large scale data management techniques for multi‐physics simulations. He has been awarded the Lichten Medal from the American Helicopter Society for his pioneering CFD studies on the BERP helicopter rotors, the Army Superior Civilian Service Medal for his lead role in the use of CFD to study and alleviate vibratory load problems on the Apache‐Longbow and Comanche Helicopters and is an Associate Fellow of the AIAA.

In Situ Post-Processing with VisIt, Libsim, and FieldView
Speaker: Brad Whitlock, Applied Research Group, Intelligent Light
The widening gap between compute performance and the ability to store computation results dictates that data analysis and visualization be performed in situ during simulation runs. Saving analysis results and data extracts offers tremendous opportunities for reduction in storage costs while also permitting greater access to data in the temporal domain. Libsim is a library which enables a fully-featured visualization tool, VisIt, to request data as needed from the simulation and apply visualization algorithms in situ with minimal modification to the application code. In this talk, the motivation for in situ processing is presented and the steps to instrument a simulation using Libsim are covered. Instrumenting simulation codes with Libsim opens up new possibilities for higher productivity workflows such as automatic creation of FieldView extract databases (XDBs) which can be visualized efficiently using the post-processing tool FieldView.
Our most important Aerospace Meeting of the year is underway. During SciTech, we are meeting with our users, demonstrating new product capabilities, and bringing IL and guest speakers to our booth for conference attendees.
- See the latest capabilities in FieldView 15
- Our all new XDBview, a powerful, free viewer for XDB files will be shared publicly for the first time
- We’ll share the latest developments using VisIt including in-situ post processing examples
Specially invited guest speakers will share some of their work in a personal, small audience setting in our booth. Intelligent Light staff will provide detailed information about the latest from our company. All speakers will be available for personal discussions.
For our Japanese speaking customers we’ll have a special presentation session in Japanese. Also, our new Asia Pacific Technical Office lead will be at the booth to present and answer questions.

Many of our customers depend on HPC every day. Our direct involvement with customers working at the leading edge of HPC driven engineering is making people vastly more productive as they harness the power of HPC.
Successful examples of cloud-based HPC for CFD use. Data management and workflow engineering are important to the success of cloud-based CFD. Presented by Steve Legensky, General Manager and Founder, Intelligent Light.
Steve Legensky, our General Manager and Founder, was recently invited to provide examples and successful strategies for cloud-based HPC. The talks were delivered for the SC14 HPC Impact Showcase and the HPC User Forum in Seattle.
Recognizing that CFD Solver Codes are often well suited to running in the cloud, CFD remains problematic for many because the results files can be very large and there can be many. Effective analysis of these files essential to the CFD workflow and is the way users gain understanding. Overcoming the constraints requires both data management and workflow engineering to deliver on the promise of on-demand HPC for CFD.
