| # DeepJEB++ |
|
|
| A foundation-model-driven 2D-to-3D data-augmentation dataset for structural |
| engineering design. **15,360** simulation-labeled jet-engine brackets, generated |
| by adapting Stable Diffusion v1.5 and TRELLIS, each paired with automatically |
| computed linear-elastic finite-element labels under four load cases. |

| ## Contents |
| | Path | Description | |
| |------|-------------| |
| | `1_surface_meshes/` | 15,360 surface meshes (`.obj`, native ~50k verts) | |
| | `2_boundary_conditions/` | Four-bolt + loaded-clevis interfaces (vertex indices, mm frame) | |
| | `3_fea_fields/` | Per-case surface FEA fields (`.npz`): displacement `U`, von Mises `vm` for 4 loads | |
| | `deepjebpp_labels.csv` | Scalar labels: mass, per-load max displacement & 95th-pct von Mises | |
| | `metadata.json` | Material, load cases, units, layout | |
| | `README.txt` | Full human-readable specification | |
|
|
| All field/BC entries are at a consistent 25k FEM-mesh density. BC node indices |
| reference `3_fea_fields/<case>.npz` `surface_points` (25k), not the native `.obj`. |
|
|
| ## Load cases (Ti-6Al-4V, linear static) |
| vertical 35.6 kN | horizontal 37.8 kN | diagonal 42.3 kN | torsional 565 kN-mm |
