In this paper, a method for automatic hexahedral (Hex) mesh generation for electromagnetic field analysis is presented. In this method, the shape recognition technique and the tree method are used. Utilizing the shape recognition technique, a mesh is generated in a complicated analysis domain, and a high-quality Hex mesh is obtained. By using the tree method, control of the mesh density is easily enabled. In this proposed system, a modest amount of input data is necessary, such as object parameters and the mesh density data.
