Land-Speed Record Attempt Uses High-Fidelity, High-Speed CFD
In 1963, Craig Breedlove set the world land-speed record in the Spirit of America, a record that he would later reclaim several more times in the next two years. Fifty years later, Breedlove has decided that it is time to bring the title back to America. In a new team led by Breedlove, the Spirit of America is being revived with the goal of once again claiming a new world record for land-speed vehicles.
Historically, land-speed vehicles were shaped by
Leveraging Pointwise, TotalSim generated a hybrid grid, balancing mesh generation time and solution accuracy. Pointwise’s structured and unstructured meshing techniques coupled with T-Rex (anisotropic tetrahedral extrusion) were used to generate layers of unstructured hexahedra and prisms, helping to reduce the overall cell count and improve grid quality. Additionally, TotalSim was able to exploit the flexibility of Pointwise and manually adapt the grid to help resolve shock structures and more accurately predict vehicle performance.
Discover how to:
- Simplify a complex geometry using layers for
- Resolve areas of high curvature using structured meshing techniques
- Automatically generate contiguous viscous layers of unstructured hexahedra and prisms
- Effortlessly add local refinement to an existing volume mesh to improve solution accuracy
- Rapidly assess high-speed vehicle performance on a limited budget
Travis Carrigan joined Pointwise as a senior engineer after completing his M.S. in aerospace engineering at The University of Texas at Arlington in May 2011 where his graduate research involved aerodynamic design optimization. Currently, as Manager of Technical Sales, Mr. Carrigan works with prospective customers and demonstrates how Pointwise software can be used to improve their CFD process. He also produces technical marketing content and works with customers and software partners to demonstrate best practices in grid generation, solver setup, and solution post-processing for a variety of industries.
Andy Luo is a graduate of the University of Southern California where he received a BS in Aerospace Engineering and an MS in Aerospace Design. Andy spent 6 years with Swift Engineering where he spearheaded their CFD capabilities in both Automotive and Aerospace design. During that time he achieved many aggressive milestones such as aiding the design of an aircraft from paper to first flight in 200 days, generating a 1 billion cell unstructured unified mesh on a
In 2012 Andy began working with TotalSim to further their Aerospace capabilities. He is currently working on many exciting developments using OpenFoam and Pointwise.
