Formula 1 racing, CFD, and Wind Tunnels

HPC Wire has a great article on the rules for computational fluid dynamics and wind tunnel testing in Formula 1 racing. It's surprising to learn the sports' governing body restricts CFD usage to 25 teraflops. Racing directors have complained about the restrictions, feeling it inhibits the use of the best techology and pushes things back by ten years.

Restrictions are in place for wind tunnel usage as well, and some have advocated for moving entirely toward CFD-only testing. However, an analysis by one team principal didn't find a huge cost savings in doing away with wind tunnels, and predicts the money would merely shift to the CFD. As well the racing community would have a hard time seeing the phasing out of wind tunnels, a long-preferred tool for racing teams.

As for the CFD controls, some have proposed shifting the rules from restricting teraflops toward controling energy bandwidth, giving teams more freedom over their computing setups.

The World of FEA Simulation at Predictive Engineering

Here's a great overview of our services. It shows some classic stress analyses that we've done over the last several years.

This short overview animation presents project work on:

  • High-torque U-joint for a steel mill leveler
  • Vibration analysis of a metal forming tool (beer can domer)
  • Stress and vibration optimization of a space frame structure (car wash frame)
  • Nonlinear buckling analysis of a two-person submarine
  • Vibration optimization of paper mill machine component
  • Stress and fatigue analysis of 50 kW wind turbine blade hub, generator shaft and nacelle.


Predictive Engineering has done over 600+ FEA simulation projects in its 20 years in business. Take a look at some of our FEA consulting services, and as always, feel free to contact us with any questions!

FEA Simulation of Medical Devices using Advanced Nonlinear Analysis

Here's a video compilation of our FEA simulations of medical devices using advanced nonlinear analysis.

In all cases, these projects were benchmarked against experimental results and shown to be in tight correlation.

As an added bonus, the music is nice too!

Complex analysis demands were only part of the challenge for these projects since the medical industry also requires extensive documentation and quality assurance that the models are built per specification.

Additionally, in several cases the clients required that an accuracy assessment be performed prior to the correlation with experimental results. It was an interesting and enlightening twist that a prediction was required of the model’s precision prior to the divulgement of the experimental data.
