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
