Abstract

fetched live from OpenAlex

This article summarizes different levels of simplification for nonlinear and hysteretic <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$B$ </tex-math></inline-formula> – <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$H$ </tex-math></inline-formula> curves intended to be used in finite element modeling (FEM) simulations of induction heating processes. Models based on coenergy are first shown and compared to the idea of fitting an equivalent complex permeability from nonlinear time-transient 1-D simulated results. A simple algorithm based on the reworked diffusion equation system is presented in detail and allows obtaining a new power-equivalent model leading to nearly zero error on power density profiles in 1-D problems for both eddy current and hysteresis losses. The equivalent complex permeability obtained is then used as a property of a given material for time-harmonic (TH) simulations in 2-D and 3-D, leading to smaller errors on losses than coenergy-based models and a much smaller computational cost compared with time-transient simulations.

Full frame distilled prediction

Teacher imitation

Not 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.
