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.

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
