Abstract
This paper presents an approach to using domain decomposition (DD) for time-stepped eddy-current analysis of induction machines. The approach uses the transmission line modeling (TLM) method to linearize the nonlinear field equations, producing a stiffness matrix that is more amenable to decomposition than that obtained by using a Newton-Raphson approach. Using a direct solver, the paper compares the approaches and shows that the proposed approach can offer simulation times that are significantly shorter than those for the traditional Newton-Raphson approach. The paper describes the steps necessary to implement the TLM-DD approach for time-stepped eddy-current analysis of induction machines. Test results for steady-state and dynamic conditions are provided.

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
