Abstract
A multiscale finite element model with subgrid-scale spatial homogenization and stability estimate for time discretization in the context of magnetostrictive composite thin-film micromagnetics are reported in this paper. Developments of the phenomenological microscopic constitutive model and the subsequent multiscale approach are aimed at analyzing the formation of magnetic domains in Terfenol-D/epoxy thin film under transverse magnetic (TM) mode of excitation. The phenomenological constitutive model is based on the density of domain switching (DDS) of an ellipsoidal inclusion in a unit cell. The subgrid-scale spatial homogenization works as a method of upwinding the small-scale micromagnetism and magnetostriction to the larger length scale. Numerical results indicate complex features of this thin-film dynamics, such as the formation of connected domains.

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
