Abstract
The present study focuses on the development of the methodology necessary for the study of fluid-structure interactions between a square cross-section cylinder and a turbulent cross-flow. The square cylinder is simulated in three configurations: 1) stationary, 2) undergoing prescribed vertical motion, and 3) undergoing autonomous vertical motion. Motion of the square cylinder through the computational domain is facilitated through a method of localized mesh deformation, which deforms the control volumes immediately above and below the square cylinder as it moves. Results for prescribed vertical motion of the cylinder, governed by sinusoidal equations of motion, are compared to those from published literature and a substantial agreement is achieved. In order to simulate autonomous motion, a vibration model is implemented providing direct application of the shear and pressure balance around the square cylinder to the motion of the cylinder.

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
