Abstract
This paper applies three shape parameterization techniques to few design cases typical in aerospace studies in order to quantify the effect of shape parameterization on automatic aerodynamic shape optimization. The three methods in study are mesh points, B-spline surfaces and the Class function / Shape function Transformation (CST). Given the extensive prevalence of CFD in aerodynamic design, it is of interest to study the efficiency of parameterization approaches and compare them in terms of accuracy and performance aspects of the shape optimization process. Initially, the complete formulation of the optimal design problem for the Euler equations is presented. Then, the implementation of these surface representation methods is explored and finally, results are presented for three-dimensional inverse design and drag minimization problems.

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
