Supporting dataset for few-shot target-local reduced-order modelling of vortex-induced vibration

This dataset contains the numerical data supporting the principal quantitative results and figures reported in the manuscript “Few-Shot Target-Local Reduced-Order Modelling of Vortex-Induced Vibration: Wake, Structural Response and Operational Lock-In Prediction”. The archive includes CSV files for spatial-transfer diagnostics, few-shot calibration, temporal-memory comparison, held-out field and response errors, conformal calibration, operational lock-in boundary refinement, and a representative response trace. It also includes one compressed NPZ file containing the representative wake-field snapshot used for field visualisation. The dataset corresponds to a two-dimensional elastically mounted circular-cylinder VIV configuration at Re = 100, mass ratio m* = 2, and damping ratio ζ = 0.01.
