In this paper, an extension of previously developed 2D.dynamic bubble system for 3D automatic finite element mesh generation is presented. Initially, a set of nodes inside the analysis domain is generated using a physical bubble system based on the law of dynamics, followed by automatic generation of tetrahedral finite elements according to the Delaunay algorithm and utilizing previously generated nodes. The proposed method introduces an improved procedure for setting initial position of each bubble, and for definition of bubble's radii, which decreases the computation time significantly. Additionally, it requires modest amount of input data and provides high quality meshes with controlled mesh densities fast and easy. Several example meshes generated by the proposed method are also presented.
