Open publisher page 0 citations

Abstract

A meshless method is a numerical method which was developed recent years. There are many different methods in constructing the shape function. This article focuses in two methods widely used, namely MLS(moving least-squares) method and SPH(smoothed particle hydrodynamics). The article lists the different methods and contrasts the difference between the two interpolate function. In the end numerical examples are used to compare the accuracy of the proposed methods. [
