The Data Portal team has run into some unexpected issues with the underlying infrastructure used for data storage. We are working on mitigating the issues and resuming data migration as soon as possible. Tentative return to operations timeframe is mid-July. Any updates to this timeline will be posted on the site banner. We apologize for the inconvenience. If you have any questions or concerns, please contact support@nas.nasa.gov
Exajet Data Portal
Time-series AMR CFD simulation of a large civilian transport in landing configuration
Welcome to the Exajet Data Portal
The Exajet is an Adaptive Mesh Refinement (AMR) Computational Fluid Dynamics (CFD) dataset. The simulation models half of a large civilian transport, split on the left-right symmetry plane (also known as "semi-span"), flying in a landing configuration (landing gear and flaps down). The particular type of AMR used in this simulation is similar to an octree, but without a single root, sometimes referred to as a "forest of octrees". There are 656 million hexahedra in the mesh and 423 snapshots in the time series. The mesh topology does not change over the time series. The solution provides density and velocity components associated with each hexahedron in the mesh (sometimes referred to as "cell centered" data). This dataset was produced by the PowerFLOW CFD solver and is provided courtesy of Dassault Systèmes for visualization research purposes. Please acknowledge Dassault Systèmes for their generosity in your publications.
