ConJEB: A Large Elastic Contact Jet Engine Bracket Quadratic Program Dataset

Abstract

This dataset contains large-scale, sparse quadratic programs (QPs) derived from physically-based animation scenarios with contact interactions. It extends the SimJEB dataset (Wahlen et al. 2021) by introducing explicit contact handling: the abstract contact force in the original GE Jet Engine Bracket Challenge model is replaced with a detailed cylinder mesh pin. This modification yields realistic large-scale sparse QPs with hundreds of thousands to millions of degrees of freedom. The dataset is designed to enable fair, reproducible benchmarking and evaluation of QP solvers in computer graphics and related fields.
