Abstract
We have developed a three-dimensional model of free surface flows that can accommodate the presence of arbitrary-shaped obstacles in the flow. The model is an extension of one developed earlier by Bussmann, Mostaghimi, and Chandra [1]. To validate the model we simulated the impact of a 2-mm-diameter water droplet landing with low velocity (~1 m/s) on tubes ranging in diameter from 0.5 to 6.35 mm. Computer-generated images of droplet deformation after impact agreed well with photographs. Droplets landing on the largest tube (6.35-mm diameter) clung to the solid surface following impact. On smaller tubes there was not enough surface area for the liquid to remain attached, and droplets fell off after impact, disintegrating into several smaller droplets as they fell. The number of droplets produced after breakup was sensitive to the location of the impact point on the tube surface.

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
