SimJEB: Simulated Jet Engine Bracket Dataset

This paper introduces the Simulated Jet Engine Bracket Dataset (SimJEB): a new, public collection of crowdsourced mechanical brackets and accompanying structural simulations. SimJEB is applicable to wide range geometry processing tasks; complexity shapes in offer challenge automated cleaning meshing, while categorical labels simulations facilitate classification regression (i.e. engineering surrogate modeling). In contrast existing shape collections, SimJEB's models are all designed for same function thus have consistent loads support conditions. On other hand, more complex, diverse, realistic than synthetically generated datasets commonly used parametric model evaluation. The designs were derived from submissions GrabCAD Challenge: an open design competition with over 700 hand-designed CAD entries 320 designers representing 56 countries. Each has been cleaned, categorized, meshed, simulated finite element analysis according original specifications. result 381 high-quality application-focused advancing geometric deep learning, modeling, related tasks.
