Abstract
Mesh adaptation relies on an error estimation process. Error estimators should properly take into consideration the contribution from both numerical and modeling related errors. Numerical dissipation plays an important contribution to the effective modeled turbulent kinetic energy (TKE), and must be accounted for. In the present paper, several error estimators for LES are implemented and compared. Two approaches are applied for the estimation of numerical TKE employed by error estimators. The validation of the periodic hill test case was carried out for the coarse, the fine and the adapted grids. Numerical results are validated through a comparison against reference LES and experimental data. We employ and demonstrate the use of various error estimators for mesh adaptation.

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
