Example text
Moving least-square (MLS) interpolation is used to construct the shape function’s values, which have high continuity in the problem domain. To evaluate the accuracy of the method as an alternative meshless method the development and theory of this new approach is presented in the context of the solution of 2D elliptic equations. Numerical results show that the method possesses high accuracy with low computational effort. Keywords: meshless method, Discrete Least Square, elliptic problems. 1 Introduction The idea of using finite difference simplicity and finite element capability of handling complex geometries are the subject of many researches.
6]. Atluri and Zhu [7] and Zhu et al. [8] suggested the local Petrov-Galerkin and local boundary integral equation (LBIE) approach in which integration is performed locally on each subdomain. A common feature of all these methods is the need for numerical integration requiring a mesh of quadrature points in the domain. Construction of appropriate integration cells, however, is a difficult job and can make meshfree methods less effective. For these reasons, Beissel and Belytschko [9] suggested a nodal integration procedure instead of using Gaussian quadrature in establishing the coefficients of the system of equations.
