# DeepJEB: 3D Deep Learning-Based Synthetic Jet Engine Bracket Dataset
This is the Hugging Face distribution of **DeepJEB**, a synthetic 3D jet engine
bracket dataset of **2,138 designs** with paired geometry and finite-element
analysis (FEA) results, generated from the SimJEB seed set via a DeepSDF-based
generative model and an automated simulation pipeline.
This repository mirrors the official DeepJEB v1.0 release. To keep the ~68k
component files practical to host, each component directory is distributed as a
per-component compressed archive (`.tar.gz`) that extracts to the original
directory layout.
## Components (extract each archive)
| Archive | Extracts to | Contents |
|---|---|---|
| `BRep.tar.gz` | `BRep/` | B-Rep CAD models (`.step`) |
| `SurfaceMesh.tar.gz` | `SurfaceMesh/` | Tessellated surface meshes (`.stl`) |
| `VolumeMesh.tar.gz` | `VolumeMesh/` | Second-order tetrahedral volume meshes (`.vtk`) |
| `FieldMesh.tar.gz` | `FieldMesh/` | Meshes carrying FEA field results |
| `Field.tar.gz` | `Field/` | Nodal field data |
| `Scalar.tar.gz` | `Scalar/` | Scalar simulation results (`.csv`) |
| `Image.tar.gz` | `Image/` | Multi-view rendered images (`.png`) |
| `SolverDeck.tar.gz` | `SolverDeck/` | Solver input decks |
| `Metadata.tar.gz` | `Metadata/` | Per-design metadata |
Example: \`tar -xzf BRep.tar.gz\` -> \`BRep/\`
