UT Knoxville's James Coder - An agent of change in aviation

We are excited to welcome Professor James Coder and his computational aerodynamics research team at the University of Tennessee, Knoxville as a new University Partner for 2017-18. 

Professor James Coder, Intelligent Light University Partner

NASA recently selected Professor Coder to lead a team pursuing aviation breakthroughs designing an ultra-efficient aerodynamic wing enabling substantial reductions in fuel or energy consumption. Funded by NASA's Aeronautics University Leadership Initiative, the team includes researchers from Penn State University, Texas A&M University, the University of Illinois Urbana-Champaign, Rutgers University, the University of Wyoming and two aviation companies—the Boeing Corporation and Airfoils, Inc. Many of these organizations are also Intelligent Light customers and FieldView users.

"Potential outcomes of the research could include revolutionary technologies, operational concepts, design tools, models, or other advancements we can't even begin to characterize today," said Doug Rohn, director of NASA's Transformative Aeronautics Concepts Program. 

“ULI... leadership in innovation to contribute to our nation’s aviation community,” - Doug Rohn, NASA

A longtime user of FieldView, Dr. Coder uses FieldView throughout the CFD workflow in conjunction with the team's CFD solvers, OVERFLOW 2 and SU2. 

  • Engineers use FieldView to ensure their simulations are properly set up, visualize the models before committing to simulation runs and for debugging input files.
  • During solver runs, the team uses FieldView to verify correct qualitative solution behavior is present in the code, and to ensure that boundary conditions are being properly enforced.
  • Visualizing results post-processed with FieldView provides high quality images and interactive capability to support interrogation by the engineers. Common visualization tools include surface contour images, constant-coordinate planes/slices and isosurfaces.
  • Much of the group's current research pertains to unsteady flows with resolved turbulent content, FieldView is used to generate isosurfaces of Q-criterion to explore the structure of the turbulence and to spot-check on the length scales being resolved.

"Creating a better wing—one with less drag, one that is more efficient—is where we can really make a difference. This is a game changer for aviation."

James Coder, Assistant Professor of Aerospace Engineering
University of Tennessee, Knoxville

Dr. Coder and Intelligent Light have participated together in the AIAA High Lift Prediction and Rotorcraft Hover Prediction Workshops for several years.

NVIDIA and Intelligent Light Pushing Ahead with In Situ Rendering on Servers

NVIDA developer blog has a feature about server side rendering featuring our work with customers such as Daimler AG.
"Intelligent Light and Daimler AG use server-based pipelines to analyze the results of their large-scale vehicle simulations. To validate thermal operating bounds when designing new vehicles, Intelligent Light's FieldView can be used to visualize the results of highly-parallel simulations. Sifting through the 15 terabytes of data from this simulation is much more quickly done on the server that ran the simulation, after which the salient time steps can be extracted and used to visually communicate results.​"

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

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.
