Abstract
This study analyzes ship hydrodynamics in hurricane waves using the 3D time-domain Rankine source method, simulating hurricane JUAN as an extreme condition. The boundary dynamics are updated to capture the instantaneous disturbed wave with transient wetted body surface. The elastic mesh technique and remeshing technique are simultaneously applied to guarantee the orthogonality and optimisation of the mesh. Convergence studies involving mesh size and time step, along with experimental comparisons, confirm the high accuracy and stability of the algorithm. The disturbed free surface, hull surface with large motion, and pressure and velocity field are visualised to highlight the nonlinear characteristics. In addition to the wave spectrum of hurricane JUAN from the Canadian Hurricane Center, three other frequently used spectra are used, and their load responses are analysed statistically. Finally, we discuss the applicability and limitations of applying the current method in a scenario involving hurricane waves.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
