Digital Engineering: CFD in Formula 1 Racing, highlights contributions by Intelligent Light

Seeking Aerodynamic Perfection in Pixels and Wind

F1 Teams Look for Aerodynamic Advantages in Wind Tunnel Tests and CFD Simulation

Intelligent Light and FieldView have long been delivering results for the demanding world of Formula 1 engineering. In the October issue of Digital Engineering, Senior Editor Kenneth Wong has two articles exploring the way that CAE is used in Formula 1. 

In the 1960s, F1 cars began to sprout wings. The so-called airfoils operate much like aircraft wings, but in reverse. Whereas airplanes use their wings to create lift, race cars use theirs to create negative lift, or downforce. "The most obvious aerodynamic devices on a Formula One car are the front and rear wings, which together account for around 60% of overall downforce (with the floor responsible for the majority of the rest)," FIA explains.

For most F1 engineers, the race began long before the car's tire touches the track. Their quest for aerodynamic advantages began in computational fluid dynamics (CFD) programs and wind tunnel tests.

"The role of FieldView is from when the solver run ends to when the engineer makes a decision. The software focuses on reducing the movement of results files which, in the case of F1 teams, could be massive. In minimizing data movement, it increases the CFD solution's performance and nimbleness. The software also emphasizes data management, allowing small packages of data to replace large results files while maintaining full numerical fidelity."

"Formula One puts more stress on CFD than anybody else we know. We work with NASA, Boeing, Lockheed, and the Department of Energy, but F1 demands daily turnaround on multi-million-cell models to understand the smallest design details or the impact of weather. They want both fidelity and
speed."

Altair Announces Availability of FieldView Express for the Altair Partner Alliance

 Powerful CFD Post-Processor Enriches Altair Partner Alliance Offering

FieldView Strengthens HyperWorks CFD Post Processing Automation and Design Capabilities with Reduced Cycle Times



Intelligent Light has been selected by Altair to extend their CFD post-processing capability by delivering FieldView Express, building on a relationship that already provides AcuFieldView to Altair's AcuSolve CFD users. The Partner Alliance provides on-demand FieldView Express capabilities to Altair customers performing CFD with a variety of solvers. 

"FieldView Express is designed for quick and easy activation through the Altair Partner Alliance," said Steve M. Legensky, Founder and General Manager at Intelligent Light. "We hope to enable Altair's large engineering audience with the benefits of a powerful CFD post-processor in this easy to use package. Intelligent Light is proud to join the APA, building upon our relationship with Altair through which we provide AcuFieldView for the HyperWorks® CFD code AcuSim."

With FieldView Express, it is easy to create and deliver compelling animations, visualizing your data and supporting your analyses. Videos can be saved in MP4 format, ready for use with PowerPoint or YouTube. 3D PDFs exported from FieldView Express are easily shared with clients and management and will add interactive analysis to reports and presentations. Every FieldView Express license is a parallel license and parallel processes enable faster data reads allowing users to tackle problems of greater size and fidelity than they could have attempted previously. 

"We are pleased to further extend our partnership with Intelligent Light on CFD post processing," said Stephen Cosgrove, VP of CFD Business Development at Altair. "Our customers have told us they use multiple CFD solvers to perform their work. FieldView Express with its support of multiple solver readers allows them to standardize their CFD post processing on the most powerful, solver neutral CFD post processor available. This will enable our customers to achieve a greater degree of CFD post processing automation which will allow them to engineer better designs with reduced CFD cycle times."

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.

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.
