Abstract :
A 3-D mesh generator for finite element analysis of electromagnetic field problems has been developed. The software is capable of handling complex topologies such as the organs of the human body. The grid is optimized by performing Delaunay correction. The use of digital image processing techniques is suggested to extract topological information from images. This information is used for identifying the regions of the model by plating initial nodes on the surfaces. An application example shows a simplified model of the human thorax created using the grid generator. It should be noticed that this problem includes most of the difficulties encountered in 3-D mesh generation for the finite element method
