arXiv:2511.15684v2 Announce Type: replace-cross Abstract: Foundation models have transformed machine learning for language and vision, but achieving comparable impact in physical simulation remains a challenge. Data heterogeneity and unstable long-term dynamics inhibit learning from sufficiently diverse dynamics, while varying resolutions and dimensionalities challenge efficient training on modern hardware. Through empirical and theoretical analysis, we incorporate new approaches to mitigate these obstacles, including a harmonic-analysis-based stabilization method, load-balanced distributed 2D
The development of a cross-domain foundation model for continuum dynamics reflects the ongoing maturation of AI research towards tackling complex physical simulations, leveraging lessons from language and vision models.
This development is important because it addresses a significant bottleneck in applying AI to scientific and engineering simulations, potentially accelerating discovery and design across multiple physical domains.
The ability to handle data heterogeneity, unstable dynamics, and varying resolutions within a single model framework changes the paradigm for how AI can be integrated into high-fidelity physical modeling, making it more robust and scalable.
