arXiv:2210.02573v5 Announce Type: replace Abstract: Learning the physical simulation on large-scale meshes with flat Graph Neural Networks (GNNs) and stacking Message Passings (MPs) is challenging due to the scaling complexity w.r.t. the number of nodes and over-smoothing. There has been growing interest in the community to introduce \textit{multi-scale} structures to GNNs for physical simulation. However, current state-of-the-art methods are limited by their reliance on the labor-intensive drawing of coarser meshes or building coarser levels based on spatial proximity, which can introduce wro
This research addresses a fundamental challenge in applying GNNs to complex physical simulations, leveraging recent advancements in graph-based AI models.
Improved mesh-based physical simulations are critical for engineering, scientific discovery, and the development of advanced AI applications, enabling more accurate and efficient design.
The ability to efficiently learn physical simulations on large-scale meshes with fewer limitations on complexity and over-smoothing will accelerate development in fields relying on such models.
