Abstract:Meshfree method has the advantage of high accuracy and complex model computing capability and its construction of shape function does not rely on predefined element grid. The paper presents the approximate principle of global weak-form meshfree method such as element-free Galerkin method(EFGM), point interpolation method(PIM) and radial point interpolation method(RPIM). Support-domain dimensionless size, field nodes and background element grid setting are studied for the influence of calculation accuracy of meshfree method by two-dimensional Poisson equation. The RPIM and the EFGM are applie
