Mask-Morph Graph U-Net: A Generalisable Mesh-Based Surrogate for Crashworthiness Field Prediction under Large Geometric Variation

This paper introduces Mask-Morph Graph U-Net (MMGUNet), a practical approach addressing the limitation of hierarchical Graph U-Net architectures in crash simulations. It aims to improve generalisability by retaining fixed coarse graph connectivity while improving spatial correspondence, offering a faster alternative to computationally expensive finite element methods.
