ABSTRACT

Over the past thirty years, computational simulation of fluid dynamics has made huge strides in meshing of complex geometries, computational efficiency and most importantly, greater fidelity in physics models. Current trends include greater adoption of unsteady methods via LES, higher order methods and alternatives to classical CFD such as Lattice Boltzmann methods. However, the majority of engineering applications remain constrained by computational and storage resources as well as schedule and time pressure. The CFD 2030 Vision highlights the need for improved Knowledge Extraction and Data Management tools that address the scale and fidelity of exascale class problems. Perhaps most interesting, these tools will enable non-deterministic engineering (NDE) in which variations in boundary conditions, discretization and models can more realistically predict the behavior of complex aerodynamic, propulsion or power generation systems.

This talk highlights recent activities at Intelligent Light that include how to manage the massive data flows resulting from ensembles of unsteady CFD calculations, new tools that support engineering use of uncertainty quantification techniques and the latest HPC-FieldView software that combines the familiar interface of FieldView with the scalability of VisIt. Through the lens of post-processing and data analysis, we have gained a unique perspective on research and engineering use of CFD from the late 1980's through today. The talk touches on this history while giving examples of state-of-the-art petascale CFD and surveys the challenges that exascale computing is intended to address.

Visions of Exascale CFD: ASME Fluids Engineering Division Summer Meeting

IL Founder & General Manager, Steve Legensky, will speak at the ASME Fluids Engineering Division Summer Meeting​ at the Hilton Waikoloa Village, Waikoloa, Hawaii

Visions of Exascale CFD

Over the past thirty years, computational simulation of fluid dynamics has made huge strides in meshing of complex geometries, computational efficiency and most importantly, greater fidelity in physics models.Current trends include greater adoption of unsteady methods via LES, higher order methods and alternatives to classical CFD such as Lattice Boltzmann methods.However, the majority of engineering applications remain constrained by computational and storage resources as well as schedule and time pressure.The Department of Energy's Exascale Computing Project (ECP) offers the capacity for scale, fidelity and perhaps most interesting, non-deterministic engineering (NDE) in which variations in boundary conditions, discretization and models can more realistically predict the behavior of complex aerodynamic, propulsion or power generation systems.

Intelligent Light is participating in research activities aimed at managing the massive data flows resulting from ensembles of unsteady CFD calculations and implementing tools to support engineering use of uncertainty quantification techniques.Through the lens of post-processing and data analysis, we have gained a unique perspective on research and engineering use of CFD from the late 1980's through today.The talk will touch on this history but have a primary focus on state-of-the-art petascale CFD in aerospace, combustion and wind energy and survey the challenges that ECP is intended to address.

Workshop: Extract-based and In Situ Methods for HPC Enabled CFD

To be held August 3, 2017, in conjunction with the ASME Fluids Engineering Division Summer Meeting​ at the Hilton Waikoloa Village, Waikoloa, Hawaii

Workshop Objectives

This workshop will assess the state-of-the-art in CFD Visualization and Post-Processing in High Performance Computing (HPC) environments. Specifically the issues of data transfer from remote HPC resources, a comparison of remote graphics vs. extract methods, and the trend toward in situ methods. Real world examples of industrial CFD workflows will be presented that offer a path to greater fidelity and faster throughput enabling an increased use of unsteady simulation.

Presenters

Prof. Kozo Fujii, Tokyo University of Science/ ISAS-JAXA 
Revisit the Role of Research Graphics in HPC Post Processing

Yves-Marie Lefebvre, FieldView Product Chief, Intelligent Light
Unblocking Data Bottlenecks in HPC CFD with Extract-based Workflows

Steve Legensky, Founder and General Manager, Intelligent Light
In Situ: Real and in Production

Making Collaborative CFD Fly

"This method of aggregating data and standardizing the interrogation of the data, especially large scale, full 3D multiphyisics data is very, very necessary and very, very useful. This partnership is exciting and we are exploring the boundaries of what we can achieve with this."

Nathan Hariharan
Chair, AIAA Helicopter Hover Prediction Workshop

The world's helicopter community came together to study the complex physics of rotorcraft in hover using CFD. They needed a HPC collaboration hub that minimized researchers' efforts to collaborate in full 3D. We made it work for the AIAA Hover Prediction Workshop and we can make it work for you.

Join Dr. Nathan Hariharan, Chair, AIAA Helicopter Hover Prediction Workshop, Dr. Earl Duque, Manager of Applied Research at Intelligent Light, and Michael Senizaiz, ‎Chief Technology Officer at R Systems, as they explore how work done to support the Hover Prediction Workshop is yielding valuable lessons for any organization looking to streamline its CFD workflow.

Learn how Intelligent Light and R Systems provide the CFD expertise and on-demand HPC capability to make high-performance CFD workflow a reality:

  • Enable data sharing among many disparate members of the organization: CFD Engineers, Designers, Managers and Customers
  • Compare many different cases, even those with different meshes or from different solvers, etc.
  • Derive higher order features, like vortex path, automatically for comparison
  • Standardize the workflow so that input from many groups can be compared side by side, both visually and numerically
  • Utilize on-demand HPC resources to run automated post-processing workflows across all the datasets producing standardized outputs and enabling collaboration

A live Q & A with the speakers will follow the presentation.

When: Tuesday, May 9, 2017, 2:00 PM Eastern

Harnessing the power of HPC for success in CFD

"To achieve 45 seconds of CFD at 60 Hz, we used VisIt/Libsim in situ to create extracts that were 21X smaller than the volume files, wall clock times were 10X less to produce the XDB files (extracts) and transfer times and space requirements were also greatly reduced. We were then able to post-process in hours what had been taking days."

Intelligent Light will hold a one-day event on harnessing the power of HPC for CFD engineers. New methods for handling large CFD data sets will be presented with a special focus on using data computed on remote HPC resources. Case studies of innovative solutions in use by our clients today will provide concrete examples of how we can put the same technologies to work for you.

You will learn:

  • How extract-based workflows are being used in industry to unblock data bottlenecks
  • How in situ and extracts can help you increase fidelity: finer meshes, more transient time steps and the ability to explore more parametric options
  • How to take full advantage of remote HPC with a combination of local and remote rendering options and by leaving large files in place on remote systems
  • How automated report generation done in batch enables our clients to get the reports they need on time

We hope you will participate and learn how you can join the growing number of organizations that are Harnessing the power of HPC for success in CFD
