AhmedML: High Fidelity Computational Fluid Dynamics dataset for incompressible, low speed bluff body aerodynamics Contact: Neil Ashton (NVIDIA) contact@caemldatasets.org website: https://caemldatasets.org Summary: This dataset contains 500 different geometric variations of the Ahmed Car Body a simplified car like shape that exhibits many of the flow topologies that are present on bluff bodies such as road vehicles. The dataset contains a wide range of geometries that exhibit fundamental flow physics such as geometry and pressure induced flow separation of flows as well as 3D vortical structures. Each variation of the Ahmed car body were run using a time accurate hybrid Reynolds Averaged Navier Stokes (RANS) Large Eddy Simulation (LES) turbulence modelling approach using the open source CFD code OpenFOAM. The dataset contains both surface boundary, 3D volume, geometry STL and forces/moments in open source formats (.vtu,.vtp). CFD Solver: All cases were run using the open source finite volume code OpenFOAM v2212. Each case was run transiently for approximately 80 convective time units (CTU) on meshes of approximately 20M cells. Please see the paper for full details on the code and va…
