AeroZoo: A Benchmark of Well-Posed Flow Problems for Foundation Models of Aerodynamics
Unseen enclosures and boundary-condition layouts raised ISLA’s flow-prediction error by 2.4 to 9.2 times; an unseen geometry family barely changed it relative to uniform flow.
AeroZoo contains 3,815 simulated flow solutions spanning seven geometry families, eight enclosure configurations and Reynolds numbers from 10³ to 10⁸. Its canonical benchmark uses 2,816 samples with stable time means and 22 fixed, geometry-disjoint splits. On the random split, adding boundary-condition tokens cut GeoTransolver’s median velocity error from 76.9% to 8.4% of inlet speed in single-seed runs; ISLA reached 5.3% across four seeds. The authors say the data and scoring code will be released.
