1st Automotive CFD Prediction Workshop — Oxford 2019
Archive of the 1st Automotive CFD Prediction Workshop held in Oxford in December 2019, including test cases, grids and presentations.
Summary
The 1st Automotive CFD Prediction Workshop was held on 11–12 December 2019 in Oxford at St Anne’s College. Three test cases were studied: the SAE Notchback geometry, DrivAer Fastback and DrivAer Estate vehicle, all of which are described below. Meshes were created for all cases in major grid formats, including OpenFOAM, STAR-CCM+, Fluent and CGNS, in addition to geometry and surface meshes. Participants who submitted results were allocated a 15-minute presentation slot; those who wished to present relevant material, such as the wind-tunnel campaign of the DrivAer model, without computing the test cases were also able to speak. The three test cases were available for participants to compute and submit to the workshop organisers for cross-plotting and summary. Each participant who computed the cases was offered a 15-minute presentation slot to discuss their results.
Participants were encouraged to run the coarse, medium and fine meshes to demonstrate mesh convergence where possible.
