Abstract

fetched live from OpenAlex

This paper aims at developing an anisotropic mesh adaptation strategy for Large Eddy Simulation (LES) of industrial applications. Starting from the Isotropic Automatic Mesh Convergence (IAMC) strategy developed previously and using the anisotropic remeshing methodologies initially developed for RANS, we propose a novel Anisotropic Automatic Mesh Convergence (AAMC) strategy to ensure similar LES accuracy, but with fewer mesh elements than with the IAMC strategy. As with the IAMC strategy, this new strategy is designed to ensure proper mean flow resolution and that enough turbulent scales are resolved in fully turbulent regions to perform reliable LES. However, particular attention is needed to ensure that the primary instabilities leading to the transition to turbulence are correctly accounted for with the anisotropic meshes

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
