Verification Artifacts for "Physics-Informed Neural Networks for Real-Time Cavitation Risk Prediction in Dam Spillways: A Multi-Dam Benchmark Study"

Companion public deposit for manuscript HYENG-15327 (ASCE Journal of Hydraulic Engineering): "Physics-Informed Neural Networks for Real-Time Cavitation Risk Prediction in Dam Spillways: A Multi-Dam Benchmark Study". The deposit contains the verification artifacts of the study: (1) the Section 4.7 OpenFOAM/interFoam 3D VOF over-topping verification case — solver and mesh-generation dictionaries (case/system), physical properties (case/constant: transportProperties, turbulenceProperties, g), initial-condition fields, execution logs, and probe-record datasets (case/postProcessing); (2) the generic ogee-crest geometry with its parameterised generator (geometry_tools); (3) post-processing and verification scripts with tests; (4) machine-readable model configuration transcribed from Table 1 (pinn_transcribed/config.yaml); (5) the Falvey (1990) field-comparison dataset transcribed from Table A2; (6) key-results table (key_results.csv); (7) Movie S1 (VOF over-topping animation) with poster and caption; (8) the pre-registered protocol for the 12-month direct-validation field campaign (TableA5_Preregistered_Protocol.pdf, deposited before first acquisition). See DEPOSIT_README.txt for the complete manifest. Licensed under CC-BY 4.0. New in this version (September 2026): the deposit now also contains gci_three_grid_verification/, the machine-readable companion of the three-grid mesh-convergence (GCI) study of manuscript Sections 3.8.1–3.8.3 and Figs. 2–5 (Supplementary Material Section S6, Tables S9–S11). The folder provides: per-grid wet-cell field samples at t = 1.85 s (56,922 / 14,602 / 3,497 wet cells on G1-fine / G2-medium / G3-coarse); validation-line data (201 / 158 / 80 points); the derived GCI metrics (r21 = 1.926903, r32 = 1.829725; GCI21 = 0.546%, GCI32 = 0.785%) together with machine-readable CSV mirrors of Tables S9–S11; the verification and figure-generation scripts; and the four figure-atlas files (600-dpi PNG plus vector PDF). A full map of the folder is given in its README_GCI.txt; item 13 of DEPOSIT_README.txt places it in the overall deposit structure. All materials added in this version are licensed under CC-BY 4.0, consistently with the rest of the deposit. Version notes: v1.0 (2026-09-14) — initial deposit of the verification artifacts. Current version — adds item 13 of the deposit map, gci_three_grid_verification/, the machine-readable GCI three-grid verification dataset.
