Uncertainty Quantification (UQ) at ASME V&V Symposium

Uncertainty Quantification (UQ) of CFD data.

Earlier this month at the ASME V&V symposium, Seth Lawrence, a graduate student at our University Partner Northern Arizona University, presented his Master's thesis work on "Verification, Validation and Uncertainty Quantification of Turbulent Twin Jets". Seth was advised by our own Dr. Duque who maintains an adjunct Faculty position @ NAU. This event was Seth's first outing at a major international technical symposium. He did a great job of presenting (and defending) his work to the leaders in the field of V&V/UQ, such as Oberkampf, Roy, Celik and Eca. The work was a Challenge Problem sponsored by the ASME V&V 30 Committee.  GREAT JOB SETH!    

In Uncertainty Quantification (UQ), engineers utilize standardized procedures such as the ASME V&V 20 and V&V 30 guidelines to account for the effects of probabilistic inputs to a CFD simulation to arrive at a non-deterministic answer. Through UQ, an engineer could state with 95% certainty answers to their design question while justifying and documenting how they arrived at their answer.

This challenge problem was the only one at the symposium to focus on UQ. It is a key area of interest for those seeking to capitalize on information gleaned from verification & validation work in new design studies. 

To combine CFD and UQ analysis, Mr. Lawrence created an automated workflow using FieldView to post-process the results of Fluent solutions and pass data to Dakota (Sandia National Lab) and then pass data from Dakota as input to Fluent in an iterative process. FieldView was also used to visualize the CFD data to create images for the presentation and 3D PDF to share results.

"Seth did a great job presenting to the leaders in the VVUQ community. His work was well received and cited by other presenters later in the symposium.  It was gratifying to hear statements among veteran symposium participants including 'This is the first time I've seen error bars on a CFD result, very impressive.'"

Earl P. N. Duque, PhD Manager of Applied Research at Intelligent Light

Mr. Lawrence noted that he enjoyed the chance to see how the experts in this field approached the benchmark ASME turbulent twin jet numeric model validation problem.

Professor Tom L. Acker from NAU and Intelligent LIght's Earl P.N. Duque served as advisers on the project.

​Mr Lawrence used the 3D PDF export capability in FieldView throughout the development of the CFD model, allowing him to easily share results of his grid convergence study (CGI) and in the observed order of the solver (p-obs). 3D PDF files are downloadable below.

"Throughout the development of the CFD model, I made good use of the 3D PDF generator that is available in the new FieldView 16.1 package. This was very helpful in the presentation of model results, and provided the ability to easily send detailed model results of large CFD datasets in the form of a small file via email, and the recipient does not need any special software to view the 3D PDF results - fantastic!"

Seth Lawrence, Northern Arizona University

London, UK, December 15th, 2015 

Intelligent Light, the developer of FieldView 16 and provider of industry leading software and services for CFD workflows to engineering and research organizations, has joined forces with Visual Technology Services, developers of the renowned PDF3D Report Generation systems, to produce the first CFD tool with built-in 3D PDF interactive report generation features.

The flagship FieldView application is the most widely used CFD post-processing software for engineering and research. FieldView delivers scalable parallel visualization from laptops to high-performance computing (HPC), including unsteady flows, numerical analysis, extensive solver interfaces and advanced post-processing and visualization techniques.

"The FieldView 16 development team has been working tirelessly to deliver many valuable new features," commented Steve M. Legensky, General Manager and Founder of Intelligent Light. "The integration of the new 3D PDF publishing feature from PDF3D's technology will transform how our customers communicate and improve success in HPC engineering activities".

This latest software release allows 3D visuals created in FieldView to be converted into the universally, freely accessible 3D PDF format, enabling faster and easier sharing and distribution of reports to any customer, without them having to install specific software to view it. The reports enable interactive 3D review of surface contours, streamlines and legends. The report encoding methods use Visual Technology Services' highly compressed PRC (ISO 14739) technology, which can produce detailed images from large data files without sacrificing quality.

FieldView is used in a wide variety of markets including aerospace, automotive, energy and civil engineering. The popular CFD post-processor is used by engineering leaders in large organizations, by engineering consultants and by several top motorsports teams.

FieldView 16 and XDBview 2 Now Available

3D PDF export generated in FieldView and seen in Adobe Acrobat Reader® (left) and on a tablet (right). (DrivAer geometry courtesy of TU München, Mesh and simulation by VINAS with Pointwise and Helyx).

3D PDF export, faster data read, reduced memory usage and many more improvements

Just a little less than a year has passed by since our release of FieldView 15 and I am happy to announce that our new version, FieldView 16, is ready for download. While software users sometimes feel like installing a new version is not going to impact them much, I am confident that every single FieldView user will benefit from this release.

You will find that FieldView 16 is faster to read your data than previous versions and will also use less memory. Data read can easily be made even faster and more memory efficient by selecting the right Data Input option. When you don't need to perform Dataset Sampling or to compute a lot of streamlines, select "Less" Grid Processing for faster data input. In cases when you do need that kind of performance, select "More" right from the Data Input panel and you will use more memory to get better performance during you session.

FieldView 16 is the first CFD post-processor to introduce a built-in 3D PDF export. This standard format is a great way to present and share your results, allowing interactive exploration via rotation, zooming, panning and commenting in Adobe Acrobat Reader and in 3D PDF viewer apps.

Other highlights of this release include:

  • New Vertices and Shaded Vertices display types for better insight and fast performance
  • The ability to sweep surfaces coming from an XDB extract and to synchronize this operation between multiple datasets for easy animations and side-by-side comparison
  • More control over the location of Surface Flows
  • A new Growing display type for pathlines animation
  • 10x faster read times for AcuSolve users, compared to FieldView 15
  • The ability to read single-file transient data as steady-state
  • Support for results from FLOW-3D v11

We're also introducing the second version of XDBview. Our free, sharable viewer for XDB extracts, now includes the same sweep capability as FieldView 16 and can now read your CAD geometries in STL format.

To learn more about these new versions, I encourage you to read our What's New in FieldView 16 document (Japanese version).

FieldView 16 is a major release. You will need to request new passwords from Intelligent Light. FieldView 16 passwords will work for both version 15 and 16, but as of this release FieldView version 14 and earlier are no longer supported. If you need to test FieldView 16 with your data or workflows before upgrading, feel free to request additional temporary passwords and we'll be happy to provide them free of charge.

Please contact our FieldView Support Team  or your account manager for more information.
