In Situ Data Management at DOE Workshop and SIAM CSE

​As CFD datasets get larger and unsteady computation becomes more common, file I/O is an increasing bottleneck. Methods that write post-processing extracts directly from solvers as they are running have proven to be a solution to this problem. Intelligent Light has long advocated for this approach and recently we were asked to participate in activities to advance the state of the art in this area.

In January, I participated in the DOE's "In Situ Data Management (ISDM)" workshop which focused on defining areas for research intended to ease the analysis and understanding of massive simulations enabled by exa-scale computing. A workshop report is forthcoming.

In February, I was invited to present at a mini-symposium at the SIAM CSE 2019 meeting aimed at avoiding the big data problem through in situ techniques.

Application of a CFD Uncertainty Quantification Framework for Industrial-Scale Aerodynamic Analysis

Wed, Jan 09, 5:00pm - 5:30pm, Torrey Hills

John Schaefer and Andrew Cary of The Boeing Company and Earl Duque and Seth Lawrence of Intelligent Light

In a joint effort between the Applied Research Group (Intelligent Light) and Boeing Research and Technology (The Boeing Company), the application of the latest developments in Uncertainty Quantification (UQ) are demonstrated as case studies for industrial scale CFD problems. Starting with a 2D NACA 0012 airfoil at zero lift, then moving to a 3D full-scale aircraft in high lift configuration, the latest UQ frameworks are implemented to determine numerical and model input uncertainty. This effort provides a step towards standardizing the use of UQ as a design and engineering tool to build confidence and reliability in scientific computational engineering and design.

Assessment of Model Validation and Calibration Approaches in the Presence of Uncertainty

Thu, Jan 10, 4:00pm - 4:30pm, Harbor H

Nolan Whiting and Christopher Roy of Virginia Polytechnic Institute and State University, and Earl Duque and Seth Lawrence of Intelligent Light

This paper discusses the investigation and implementation of various methods for quantifying Model Form Uncertainty​ (MFU) in scientific computing. Metrics were obtained through rigorous implementation of several MFU methods to produce comparison studies that quantify the conservativeness of each method. The findings include which methods perform best under different circumstances and provide a guide to best practices when choosing a method for quantifying the model form uncertainty in a computational UQ study.

Summary of 2017 SciTech Computational Environments Special Session Toward the CFD Vision 2030

Fri, Jan 11, 9:30am - 10:00am, Vista B

Andrew Lofthouse, CREATE AV Team, Earl Duque, Intelligent Light, Roger Davis, University of California‚ Davis

Computational Environments can be defined as the hardware and software required to efficiently use high performance computing resources and to easily extract knowledge from that data. As such, they underlie nearly all large-scale simulations. The CFD Vision 2030 report published recommendations for advancements in all areas of computational fluid dynamics that are needed in order to take advantage of Exascale hardware that is expected to be in operation by the year 2030. This paper summarized a special session held at SciTech 2017 sponsored by the Meshing, Visualization and Computational Environments technical committee that looked in more detail at the current status of computational environments and where additional research is required in order to efficiently use Exascale machines.

The session consisted of technical presentations and a question and answer period with a panel of invited experts. Computational environments are vital for efficient use of heterogeneous hardware architectures, large-scale data management, interfaces between multidisciplinary domains, uncertainty quantification and error analysis, as well as automation of complex simulations.

Spectre: A Computational Environment for Managing Total Uncertainty Quantification of CFD Studies

Fri, Jan 11, 10:00am - 10:30am, Vista B

Earl Duque and Seth Lawrence of Intelligent Light

The future of uncertainty quantification as a tool for computational engineering and design hinges on the management, execution and visualization of complex data-driven workflows. Whether the data is historic experiments or modern computational simulations, UQ workflows require onerous dedication to the management and synchronization of all available data. To address the needs of complex UQ workflows, the Applied Research Group at Intelligent Light has developed Spectre: A Computational Environment for Managing Total Uncertainty Quantification of CFD Studies. By encompassing a database, server and user-interface into a RESTful web deployed platform, Spectre provides seamless integration of data management, solver execution and visualization.

FieldView 18 adds realistic rendering, reflected environments and unlimited colors to bring your results to life. Increased performance, new data readers and advances in our CFD Data Analytics capabilities make FieldView 18 the fastest, most powerful FieldView ever. ​

Bring CFD to Life

Predefined Materials Provide an Intuitive Materials Selection

Easily apply predefined material properties from the new Materials tab. No need to adjust a long list of light reflection settings. Choose between six predefined reflected environments for a realistic effect that suits your application. Then add a background image to further increase the realistic impact of your scene.

Editable Material Colors - Choose from Over 16 million Colors

Materials like glass and plastic come in various colors in real life. FieldView 18 lets you color your surfaces with a virtually unlimited pallet. Hit the color wheel icon to select from over 16 million colors. Save and reuse your favorites. There is no limit to the number of colors used per session.

Filter Bar for Boundary Types - Easily Group Boundary Conditions by Name

Type a word in the filter bar and the list of Boundary Types automatically updates. Hit Select All, then OK, and the corresponding Boundary Surface gets created. In the same way, Deselect All operates on the filtered list. The Filter Bar supports wildcards and has been designed for performance on 1,000s of entries.

Data Analytics - Intelligent Light Continues to be at the Forefront of Data Analytics Applied to CFD

FieldView 18 comes with new MATLAB/Octave scripts for querying CFD results over time, performing a POD analysis and writing the results to PLOT3D. This allows you to close the loop and visualize modes as Iso Surfaces in FieldView, as shown in this image. Save videos as individual images to run an analysis on the pixels and avoid having to resample your data.
