摘要

“本文致力于介绍无网格方法——无单元伽辽金方法(EFGM)的一些性质,该方法在罗马尼亚鲜为人知,使用较少。尽管有限元方法(FEM)得到了大量使用,但出现了新的数值方法,其中包括无元伽辽金法是一个。该方法属于无网格方法,它基于一种称为mooving最小二乘法(MLSM)的近似方法。本文综合介绍了EFGM的基本原理。本文还介绍了我们的一些研究结果,这些结果表明了EFGM的一些基本优点。提出了一个简单的结构分析问题,但通过理论、有限元和EFGM三种方法获得了结果。结果是一个恳求和使用EFGM的模型。标题问题的答案将由EFGM的任何用户给出。“

Element-Free Galerkin Method and Finite Element Method. Which is better?
"This paper is dedicated to the presentation of some qualities of a meshfree method – Element-Free Galerkin Method (EFGM) – which is few known and fewer used in Romania. In spite of a large using of the Finite Element Method (FEM), new numerical methods appeared, among these the Element-Free Galerkin Method (EFGM) is one. This method belongs to the meshfree methods, which is based on an approximation method named mooving least square method (MLSM). This paper presents in a synthetically way the base principle of EFGM. Some results of our researching work are also presented, which demonstrate some basic advantages of the EFGM. A simple problem of structure analysis is presented but the results are obtained by three methods: theoretical, FEM and EFGM. The results are a pleading and a model for using the EFGM. The answer of the title question is going to be given by any user of the EFGM. "
