Hydrodynamic Diffraction Analysis Reports
Vessel motion RAOs from potential-flow diffraction analysis, rendered live in your browser from the de-identified Hugging Face dataset aceengineer/digitalmodel-diffraction-rao. No result values are baked into these pages.
Diffraction Analysis — select program, vessel & damping
LIVEOne report for all published series: pick the program (AQWA / OrcaWave), vessel and damping ratio from dropdowns — the series list itself comes live from the dataset, so new publications appear automatically. Six-DOF RAO plots, peaks, hydrostatics and reliability flags per series.
Presets: AQWA · drillship · ζ=0 · OrcaWave · drillship · ζ=0 · OrcaWave · drillship · ζ=5 · OrcaWave · heavy-lift · ζ=5
Diffraction Comparison — any two series
LIVEPick any two published series (across program, vessel or damping ratio) with the same dropdown selectors: overlay plots and interpolated delta statistics per DOF and heading. Flagged artifact bands are plotted but excluded from the statistics; mismatched damping or vessels are banner-flagged so differences are attributed correctly.
Presets: solver benchmark (AQWA vs OrcaWave · drillship · ζ=0) · damping sensitivity (OrcaWave · drillship · ζ=0 vs ζ=5)
How these reports work
Each page queries the Hugging Face datasets-server API at load time, computes summary statistics in-browser, and states its exact data contract (filter clause, row counts, dataset revision sha). Results are screening-grade and de-identified — vessels are referenced only by vessel_db IDs, and reliability flags travel with every row.
