Abstract
This paper presents a general monolithic nite element formulation for o w and sensitivity analysis of the unsteady uid-structure interaction undergoing large displacements. 1 We consider incompressible viscous o ws and structure undergoing large displacements. The coupled set of equations is solved by a direct implicit FEM using a Newton-Raphson procedure. A pseudo-solid formulation is used to manage the deformations of the uid domain. The formulation uses uid velocity, pressure, and pseudo-solid displacements as unknowns in the o w domain and displacements in the structural components. The formulation is rst veried on a problem with a closed form solution and then applied to sensitivity analysis of a heaving and pitching exible foil in a o w.

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
