Abstract
This work highlights a new mesh adaption procedure which takes action locally. The procedure is specially designed for the simulation of unsteady flows. The methodology is explained in a two-dimensional context but could be extended to tackle three-dimensional problems. This approach is intended to be an interesting alternative to techniques based on local mesh subdivision or fusion. The method uses the gradient recovery technique of Zhu and Zienkiewicz to estimate the spatial error, and an advancing front meshing tool to mesh the computational domain. The elements removed from the mesh, denoted seeds, are identified by their size variation predicted by the mesh adaption method. The mesh updates are triggered by several stopping criteria which also suspend the time-integration. The process is therefore completely automatic. The work presented here was carried out within the framework of the finite element method.

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
