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.
