In recent years, the object for numerical analysis becomes complicated and the meshing is more and more difficult. The Free Mesh Method, which is one of the mesh-less methods, is considered to make large-scale analysis easier without the so-called meshing method. Enriched Free Mesh Method is a revised one from the Free Mesh Method. Analysis result of the former method becomes better than analysis result of the latter. In order to reduce the computation time for meshing, we develop a new method using semi-circle with searching circle of nodes when employing the Free Mesh Method. In this paper, we describe dynamic analysis using Enriched Free Mesh Method with re-meshing.
