![The study demonstrates that spectral models, when assessed across multiple rollout steps via [latex]L2L\_2[/latex] and [latex]R2R^2[/latex] metrics, consistently outperform spatial models in predicting positional accuracy and Poisson’s ratio; this advantage is particularly evident in the norm-NLSF model, which achieves the highest [latex]R2R^2[/latex] value at rollout step 100, suggesting its superior capacity for accurate material property estimation during iterative simulations.](https://arxiv.org/html/2601.05860v1/figures/perf.png)
