Abstract
Compared to monolithic simulation methods, integrated simulation methods allow decomposition of a large and complex system into several subsystems whose behavior can either be numerically or experimentally captured considering unique capabilities of existing analysis tools. Therefore, they have been applied to multi-physics problems and analysis of large-scale complex structural systems. However, there is still a lack of a robust integrated simulation method that can be easily implemented in existing analysis tools and also ensure numerical stability. In this study, a novel integrated simulation method is proposed that not only allows seamless data exchange based on standard input and output of subsystem programs but also can achieve unconditional stability by adjusting the time integration coefficients for the interface layers between the decomposed subsystems. The stability of the proposed method is mathematically evaluated through the energy approach. Numerical evaluations of the accuracy and stability limits of the proposed method are also presented. Two application examples are provided to demonstrate potential applications of the proposed approach.

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
