Abstract

fetched live from OpenAlex

The partial element equivalent circuit (PEEC) method effectively solves Maxwell’s equations in integral form by converting electromagnetic field components into the electrical circuit domain. This article proposes a novel transmission line modeling (TLM) based parallel PEEC time-domain solver to solve nonlinear electromagnetic problems. The method substitutes both linear and nonlinear components in the standard PEEC equivalent circuit with corresponding TLM models, leading to an electrical current-based linear network and a magnetic current-based nonlinear network. The proposed TLM-PEEC method effectively decouples the nonlinear elements from the linear network, enabling individual solutions for the nonlinearities and making it highly suitable for parallel processing. Each nonlinear element is solved using parallel Newton-Raphson (N-R) iterations, and the analytical calculation of the Jacobian is presented along with the algorithm. The parallelization of the TLM-PEEC method is explored and implemented on a many-core graphics processing unit (GPU) and a multi-core central processing unit (CPU) to provide detailed field-oriented information on electromagnetic transients in a single-phase 2-D shell-type transformer. The proposed architecture was easily coupled with an external network, and the accuracy and computational efficiency of the TLM-PEEC method were verified through similar simulation results obtained from Comsol Multiphysics.

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.
