Abstract: An algorithm based on node space function for nonuniformly arranging the nodes automatically and for generating background cells is presented regarding to the shape with irregular boundary. This algorithm has the advantages of perfect adaptability to regions with irregular shape and arbitrary densification of nodes, easy implementation and less time consumption. These auto-arranged discrete nodes can be adopted to implement the numerical computation by meshless method directly and can also be used to generate background cells easily and efficiently. Furthermore, the generated background cells can also be applied to numerical result datum of posttreatment.

Key words: meshless method, node space function, background cell, numerical computation
