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

Welcome to the Cart3D Triceratops Data Portal

This dataset contains a small (1.7M hexahedron mesh) Cart3D test case for the triceratops geometry. The geometry is open source, so there are no issues passing this to outside collaborators. Cart3D is a high-fidelity flow analysis package for conceptual and preliminary aerodynamic design. Cart3D uses "Cartesian" meshes with Adaptive Mesh Refinement (AMR). The mesh is somewhat like a an octree, but without a single root node. This is sometimes referred to as a "forest of octrees". The data are "cell centered," i.e., the data are per hexahedron.

You can use this portal to download data from the Cart3D Triceratops Portal.
