Graph Network-based Structural Simulator: Graph Neural Networks for Structural Dynamics
This analysis introduces the Graph Network-based Structural Simulator (GNSS), a novel GNN framework specifically designed for dynamic structural simulations. Addressing limitations of traditional GNNs in structural mechanics, GNSS employs a local-coordinate formulation, a sign-aware regression loss, and a wavelength-informed connectivity radius. Evaluated on a clamped beam excited by a 50 kHz pulse, GNSS demonstrates superior accuracy, reproduces physics over hundreds of timesteps, and generalizes to unseen loading conditions, achieving a 5x speed-up over traditional finite element methods while maintaining high fidelity.

GNN Architecture Innovations
Local-Coordinate Kinematics: GNSS expresses node kinematics in node-fixed local frames, crucial for stability with micro-scale displacements and avoiding catastrophic cancellation in finite-difference velocities.
Sign-Aware Regression Loss: Employs a novel weighted Mean Squared Error (wMSE) that penalizes acceleration predictions with incorrect signs, reducing phase errors and improving long-horizon stability.
Wavelength-Informed Connectivity: Uses a connectivity radius aligned with physically meaningful interaction scales (e.g., bending-wave wavelength), optimizing graph construction and message passing.
Structural Dynamics Challenges
Micro-Scale Displacement Issues: Traditional GNNs operating in absolute coordinates struggle when load-induced displacements are orders of magnitude smaller than system dimensions.
Catastrophic Cancellation: Subtracting nearly equal floating-point numbers for finite-difference velocity computations leads to significant digit loss, degrading derivative accuracy and destabilizing long rollouts.
Global PDE Supervision Limitations: Neural operators and PINNs often rely on global transforms or explicit PDE supervision, which can be stiff for high-frequency short wavelengths and computationally expensive for complex geometries.
Performance & Generalization
Accurate Wave Propagation: GNSS accurately reproduces complex wave physics over hundreds of timesteps, outperforming traditional GNS.
Generalization to Unseen Conditions: The model effectively generalizes to new loading conditions not present in the training data, indicating robustness.
Significant Speedup: Achieves substantial inference speedups (e.g., 5x over FEM) while maintaining high spatial and temporal fidelity, making it a competitive alternative for dynamic simulations.
GNSS achieves substantial inference speedups compared to explicit finite element baselines, making real-time structural analysis feasible.
