Abstract
The development of a fluid-structure interaction framework is described. The framework is modular in nature, which allows for the use of existing commercial and research solvers and is used to study propulsion systems that use shape deformation such as SCUBA fins. The framework is comprised of various modules which are described and, in the case of the fluid solver module, validated. The fluid solver was used to resolve the turbulent flowfield about a 2-D circular cylinder at a Reynolds number of 140,000. The results obtained compare favourably to those reported in the literature. The fluid-structure interaction framework is then used to simulate a pitching and heaving rigid 3-D fin and a flexible fin undergoing the same motion. The results are then compared and show the eect that even limited flexibility has on the performance of the system.

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
