| Abstract: | Element-free galerkin method (EFG) is a new numerical method to solve boundary value problem(BVP). Compared with FEM, it possesses several notable advantages, such as requiring simple data, higher accuracy and higher order continuity. These advantages rely on an interpolating function based on moving least square (MLS) being adopted in EFG. In this paper, the interpolating formula is derived, some relative problems are discussed and some views about how to solve problems are put forward. Finally, an example is taken to justify our views. |
