Learn how to advance your CFD - Don't Miss IL at SC16

Intelligent Light will be in booth #4421 at SC16, the premier HPC event of the year. Intelligent Light will be contributing to the technical conference and on the exhibit floor where we will share the latest information about high performance CFD workflows using HPC. 

The considerable interest in the HPC community regarding in situ analysis and visualization is driven by the desire to save I/O costs and time, increase accuracy with fine sampling of transient analysis and full utilization of HPC resources. As a member of the ISAV Program Committee, Intelligent Light will participate in workshops bringing experience from real world work on ultra scale simulations. Join Intelligent Light presenters and authors in two sessions designed to develop in situ methods and share best practices.

ISAV 2016: In Situ Infrastructures for Enabling Extreme-Scale Analysis and Visualization

In Situ Infrastructures for Enabling Extreme-Scale Analysis and Visualization

This workshop is held in conjunction with SC16 and is chaired by Wes Bethel, Senior Computer Scientist at Lawrence Berkeley National Laboratory.  Intelligent Light's Earl Duque, PhD. serves on the organizing committee and both he and I are members of the program committee for the full day event.  The workshop features a series of short papers, presentations and discussions.  

Workshop Theme: 

The considerable interest in the HPC community regarding in situ analysis and visualization is due to several factors. First is an I/O cost savings, where data is analyzed/visualized while being generated without first storing to a file system. Second, the potential for increased accuracy, where fine temporal sampling of transient analysis might expose some complex behavior missed in coarse temporal sampling. Third, the ability to use all available resources, CPUs and accelerators, in the computation of analysis products.

The workshop brings together researchers, developers and practitioners from industry, academia, and government laboratories developing, applying, and deploying in situ methods in extreme scale, high performance computing. The goal is to present research findings, lessons learned, and insights related to developing and applying in situ methods and infrastructure across a range of science and engineering applications in HPC environments; to discuss topics like opportunities presented by new architectures, existing infrastructure needs, requirements, and gaps, and experiences to foster and enable in situ analysis and visualization; to serve as a "center of gravity" for researchers, practitioners, and users/consumers of in situ methods and infrastructure in the HPC space.

I am a co-author on this paper to be presented during the workshop, which describes a common interface that can be used to instrument simulations with multiple in situ infrastructures, including Libsim:

Special Presentation @ SC16: Extract-Based CFD Workflows Reduce Bottlenecks & Cost

Steve Legensky, Intelligent Light's Founder & General Manager has been invited to present during a special Workflow Session of the SC16 Exhibitor Forum.

Extract-Based CFD Workflows Reduce Bottlenecks and Cost
Tuesday, November 15th, 4-4:30pm 155-E

Business and engineering leaders are eager to utilize High Performance Computing (HPC) to accelerate engineering while reducing design risk. Higher core counts provide faster turnaround and the ability to perform many design evaluations. However, two issues can block success from HPC: software costs and data bottlenecks.

Intelligent Light, makers of FieldView, the premier post-processing and workflow tool for CFD, are helping customers to address both of these issues by building upon DOE's VisIt, the premier visualization tool for ultrascale systems. Our VisIt Prime gives users a robust, reliable and fully supported software release backed by Intelligent Light's first class global support team. There is no per core or per user license cost for this product.

UQ with Dakota & FieldView XDB Workflow at Overset Grids Symposium October 17–20, 2016

As CFD users increasingly exploit ultrascale HPC capability and approach the realm of exascale, they will run studies consisting of many related simulations at very high fidelity. This will give engineers and researchers both the ability and need to assess the quality of their simulations. When simulation quality has been vetted, engineering judgments and investment decisions can be made with confidence. 

Uncertainty Quantification (UQ) provides a means to support this need and Intelligent Light has been working on integrating UQ tools including Sandia National Lab's Dakota in an extract-based (XDB) workflow where processing takes place while solutions are in memory and data storage/transfer needs are dramatically reduced.

Dr. Earl P. N. Duque will present "Uncertainty Quantification with Dakota-OVERFLOW within an in situ based FieldView XDB Workflow" at the Overset Grids Meeting. Meet with Dr. Duque and Joe Oliver, Global Sales Manager, to learn how FieldView users are getting more information from their data. Put the latest in high-productivity post-processing, in situ processing and CFD data management techniques to work for you.

Intelligent Light is proud to sponsor this year's symposium which will be held at the Future of Flight Aviation Center in Mukilteo, Washington on October 17-20, 2016.

Presentation Abstract:

Uncertainty Quantification with Dakota-OVERFLOW Within an In Situ Based FieldView XDB Workflow
Authors:
Earl P.N. Duque, Intelligent Light
Dan Heipler, Intelligent Light

NASA has called out the integration of VV/UQ tools into engineering workflows as a vital component of its "CFD Vision 2030 Study". In that document, the authors assert that as exascale computing becomes available, the capability to perform many highly resolved CFD simulations will become ubiquitous, enabling the ability, and need, to perform UQ and sensitivity analysis. To address this need, this presentation summarizes current work whereby the Dakota code drives an ensemble of OVERFLOW2 jobs to explore a nested epistemic-aleatory parameter space. Concurrently, OVERFLOW2 instrumented with VisIt/Libsim creates FieldView XDB surfaces via in situ processing to reduce the data for post-hoc visualization and analysis. The presentation presents UQ concepts in general and their implementation within the current framework.

This work is sponsored by a DOE Office of Science grant (DE-SC0015162)

European Rotorcraft Forum September 5-8, 2016

Comparing many different CFD cases is often complicated by the use of differing meshes, solver codes and time intervals. Intelligent Light is working with CFD users in industry to develop and demonstrate engineered workflows to support the direct comparison of varied data.

The helicopter community seeks quality methods that allow for cost effective, accurate and timely simulations of hovering flight. The Helicopter Hover Prediction Workshop 2016 provides an opportunity to apply a standardized, automated post-processing workflow that eases dataset comparison, report generation and knowledge extraction for a diverse set of CFD results derived from varied models and solvers. 

Dr. Earl P. N. Duque, Intelligent Light's Manager of Applied Research and Yves-Marie Lefebvre, FieldView Product Chief participated in the European Rotorcraft Forum September 5-8, 2016, in Lille, France. Dr. Duque presented in the aerodynamics track and  the CFD workflow that enabled the work has applications for all CFD users.

​Direct comparisons of the CFD simulation results and the standardized post-processing scheme based upon FieldView will be demonstrated.The workflow tracks the helicopter rotor tip vortex core for quantitative comparisons while Iso-surfaces and coordinate cut planes of Q-criterion were created and saved as FieldView XDB files for qualitative comparisons. These surface extracts allow interactive viewing and direct comparisons of the predicted wakes using multi window graphical displays.

Special thanks to our partners at R Systems and Cray, Inc. for their support.
