【摘要】 无网格伽辽金法部分地摆脱了网格的束缚却不容易处理本质边界条件,而有限元法便于处理本质边界条件却需要进行网格的划分。因此,将无网格伽辽金法与有限元法耦合,充分利用各自的优点,不失为一种有效的方法。将无网格伽辽金法与有限元法进行耦合并将其应用于静电场问题的处理中,最后通过数值算例验证了该方法的可行性和有效性。更多还原

【Abstract】 The element-free Galerkin method(EFG) eliminate part of the mesh,high precision,convenient and stable post-processing,while the finite element method easy to deal with the boundary conditions.So if coupling these two methods to make full use of the advantages of both to complement each other,is a very effective method.This paper try to deal with electrostatic field problems by element-free and finite element coupling method,and establish the electrostatic field problems meshless model,then obtain function and soved.Numerical examples showing the method feasibility and effectiveness.更多还原
