Abstract
Bending-active structures, made from elastically bent materials such as fiberglass rods, offer exciting opportunities in architecture because of their broad formal palette and ease of construction. While they have been relevant since Frei Otto’s Mannheim Multihalle (1974), recent computational developments that help simulate active-bending processes have renewed interest in them. Such tools are important because they can replace time-consuming and imprecise physical modeling processes. However, physically meaningful simulations, using real materials and full scale, are difficult to create, and there are no good mechanisms to reveal when a simulation is inaccurate. This article offers a conceptual and numerical study of two popular contemporary algorithms for simulations of bending-active structures, mainly through a comparison of their results on the planar elastica. We then offer guidelines on best practice modeling settings and demonstrate possibilities and pitfalls through an architectural-scale case study.

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
