Intelligent Light and FieldView

Parallel CFD Conference - Extract-based Workflows Enable & Accelerate Large Scale Production CFD

28th International Conference on Parallel Computational Fluid Dynamics, May 9-13, 2016, Kobe, Japan  

Extract-based Workflows to Enable and Accelerate Large Scale Production CFD 
Steve M. Legensky, Founder and General Manager, Intelligent Light

As scalable computing use accelerates, the rate at which data is being generated by CFD simulations exceeds the speed at which it can be written to disk, transferred, post-processed and analyzed. It has become difficult for engineers and researchers to gain understanding via visualization, exploration and collaboration. As a result, design alternatives are not tried, research questions are not asked and simulation complexity is reduced.  The true value of HPC enabled CFD is not realized.

Extracts created in situ present a solution to this otherwise intractable problem by vastly reducing the amount of data that is written, transferred and used for visualization and analysis. In sity methods have been maturing over the years with two open source tools, VisIt/libsim and ParaView/Catalyst becoming ad hoc standards for production-level in situ CFD. However, using these methods at peta-flop and exa-flop scales present the same challenges that most codes face in moving to these extreme scales.

Intelligent Light has been involved in developing and extending VisIt/libsim for in situ and extract-based post-processing and creating a more standardized, high performance infrastructure for in situ integration into solver codes. In this presentation Steve Legensky will provide an overview of the current scaling research utilizing the Georgia Tech AVF-LESLIE reactive flow multiphysics code on large scale systems at DOE's NERSC and the TITAN system at the Oak Ridge Leadership Class Compute facility. On TITAN, over 130,000 cores were used for the solver and integrated in situ processing. 

In addition, benchmark results for production engineering examples in aerospace will be presented.

Now Available! Formula 1 & FieldView – Winning CFD Workflows

Hear it for yourself!  

On Demand Webinar now available!

Torbjörn Larsson, Creo Dynamics AB, has an impressive background in aerodynamics and CFD methodology. His track record in Formula 1, most recently at Ferrari, establishes him as a preeminent CFD workflow engineer. He has been instrumental in building up the CFD department for the Sauber F1 team and has since led the CFD teams at Sauber, BMW and Ferrari to much success in Formula 1.


Mr.Larsson presented Formula 1 workflows designed with FieldView to a group of over 100 CFD engineers at the 2015 VINAS User's Group Meeting in Shinegawa, Japan. This international audience included CFD engineers from Motorsport, Automotive Manufacturing, Heavy Industry, Government Research Agencies and Academia.

"Presenting at the VINAS UGM in Japan was an amazing experience. Japan is synonymous with both excellence in engineering and a passion for motorsports. More knowledgeable listeners are hard to find," said Mr. Larsson. "Being able to showcase to this audience how the ultra-fast CFD workflow seen in Formula One has gained further efficiency from the integration of recent FieldView XDB technology was truly inspiring and rewarding."

F1 teams are among our most demanding customers due to the need to simultaneously achieve breakthrough results in a very short time while building a robust, reliable production workflow.

Formula 1 teams demand:

  • The ability to manage huge volumes of results data in very short timeframes
  • Ongoing acceleration of their entire CFD workflow
  • Delivery of vital engineering information to the right people in the team, on time, every day.

Mr. Larsson's presentation focused on designing workflows to meet the demands of Formula 1 CFD teams where huge volumes of data and very short timeframes require innovative and robust automation. His solution includes the use FieldView XDB extracts as a way to reduce data size and achieve required throughput.​

Mr. Larsson is a fluid dynamics and CFD methodology engineering consultant at Creo Dynamics AB, helping organizations improve the efficiency of their CFD operations.

Authors Book Signing Event at AIAA SciTech: Aerodynamics Textbook Introduces Undergraduates to CFD

At this year's AIAA SciTech, Intelligent Light hosted a special community event around the recently published undergraduate level textbook "Applied Computational Aerodynamics: A Modern Engineering Approach". Authors David R. McDaniel, Russell M. Cummings and Scott A. Morton, joined us during the exhibit hall opening reception for lively conversation and to signed copies of their book for other educators, students and aerospace professionals.

Many people purchased the book from Cambridge University Press both in the exhibit hall and brought it to our booth to be signed by the gracious authors.

Intelligent Light contributed to the development of the visualization components of the text and FieldView images are used throughout. Further, students are encouraged to explore sample datasets interactively using the FieldView Demo Version.

The FieldView Demo Version is useful for educators because it allows students to become familiar with the same commercial software they are likely to use later in their CFD careers and because it is free to download and requires no license.

We'd like to thank the authors for their leadership in developing the next generation engineers for the aerospace industry. We thank them for their time and generosity in meeting with people and making this a great event.
