A new method for automatic mesh generation using dynamic bubble system is presented in this paper. The proposed method has two separate processings: one which generates nodes inside the analysis domain using physically-based system of bubbles, and the second one for automatic generation of finite elements according to the Delaunay algorithm using previously generated set of nodes. Generation of the initial nodes in the analysis region is performed using frontal method while the dynamic movement of the bubbles is performed simultaneously for the entire region. In the proposed method the density of the mesh easily can be controlled using simple exponential functions which allows obtaining desired mesh density with modest amount of input data for a very short computation time. The proposed method is applicable for automatically meshing geometrically complicated shapes and structures such as those found in various electromagnetic devices like rotating machines and transformers.
