基于EFG法的GPU加速研究综述

An Overview of GPU Accelerated Research Based on EFG Method

无网格伽辽金法(Element-Free Galerkin Method,EFG法)是无网格法(Element-Free Method,EFM)的一种,随着有限元法在解决不连续问题和结构大变形问题,例如材料的相变、材料的破坏和失效以及冲击裂纹扩展等问题遇到瓶颈,EFG法在国内外被广泛研究与应用,大量的研究显示,EFG法在求解上述问题时具有独特的优势,但也存在计算量大的劣势,同时GPU在数据处理上优势明显,所以将GPU应用于EFG法加速一直是学术界研究的热点。

Meshless Galerkin Method(Element Free Galerkin Method,EFG Method) is a meshless Method(Element-Free Method,EFM),with the finite Element Method in solving the discontinuous and large deformation problems,such as phase change material,the material damage and failure as well as the impact crack propagation problems encountered bottleneck,EFG Method widely research and application at home and abroad,a large number of studies have shown that,EFG Method has unique advantages in solving the above problems,but there are large amount of calculation of disadvantage.At the same time,GPU has obvious advantages in data processing,so it has been a hot topic in academic research to accelerate the application of GPU to EFG method.
