Abstract
Abstract We present an implementation of Hysing's ( Int. J. Numer. Meth. Fluids 2006; 51 :659–672) semi‐implicit method for treating surface tension, for finite volume models of interfacial flows. Using this method, the surface tension timestep restriction, which is often very stringent, can be exceeded by at least a factor of 5 without destabilizing the solution. The surface tension force in this method consists of an explicit part, which is the regular continuum surface force, and an implicit part which represents the diffusion of velocities induced by surface tension on fluids interfaces. The surface tension force is applied to the velocity field by solving a system of equations iteratively. Since the equations are solved only near interfaces, the computational time spent on the iterative procedure is insignificant. Copyright © 2008 John Wiley & Sons, Ltd.

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
