Although finite element method (FEM) is effective in solving partial differential equations in numerical analysis, the creation of the mesh data has and will become a very burdensome process. Therefore, meshless or element free method, which require no element or grid, are believed to be effective and efficient. Since only the nodal data are necessary, it is belived that CAD/CAE seamless system can be created using these methods. Furthermore, because of the developments made in the field of multi-media, the processing of digital image data has become very simple tasks. With these method, it is believed that the implementation of these digital images to the numerical analysis is easily achievable. This paper will discribe a prototype of such system developed by the authors, based on the element-free Galerkin method (EFGM) 2D elasticity problems. Mainly the preprocessores, where the data is constructed from CAD and digital image data, will be the main focus of this paper.
