ONE CYLinder: A Benchmark for Graph-Based Surrogate Modeling of Unsteady Bluff-Body Flows
ONECYL gives graph surrogate models a shared cylinder-flow testbed across three flow regimes.
The benchmark includes 450 high-fidelity finite-element simulations, totaling 270,000 snapshots of velocity and pressure on unstructured meshes. It varies cylinder geometries and includes Reynolds numbers, mesh connectivity, geometric descriptors, and aerodynamic quantities. The authors also provide an evaluation setup for rollout errors, virtual probes, drag, and lift. Their baseline Graph Transformer finds that level-set geometry encoding improves long-horizon generalization, while divergence regularization helps more as flows get harder. ArXiv · AI/CL/LG's note
