新的TRACE模拟器通过基于边的记忆增强颗粒动力学模拟

研究人员开发了TRACE,这是一种新颖的用于颗粒动力学的图网络模拟器,它通过将时空接触历史直接存储在图的边上来改进现有方法。这种方法利用基于注意力的消息传递和门控循环单元,可以对颗粒运动进行更准确的长时程模拟。与之前的模拟器相比,TRACE在位置和沉积误差方面有了显著降低,并且与材料点法等传统方法相比,在保持物理一致性的同时,速度有了显著提升。 AI

影响 这种新的模拟器可以通过提供更快、更准确的模拟,加速依赖颗粒动力学的领域(如土木工程和材料科学)的研究。

    TRACE:用于颗粒动力学的时空接触记忆图网络模拟器

    arXiv:2609.02991v1 Announce Type: cross Abstract: Learned graph simulators provide an efficient alternative to high-fidelity solvers for granular dynamics. However, granular motion depends strongly on inter-granular contact history, which is difficult to preserve when particle co…
