Automatic three‐dimensional mesh generation by the modified‐octree technique

Abstract

Abstract An approach for the fully automatic generation of three‐dimensional finite element meshes is presented. The method is specifically designed for use with solid modelling systems which provide a complete and unique definition of the geometry of a part. The method follows from the basic concepts of the octree encoding technique with specific modifications made to produce valid, user controllable finite element meshes. Example problems are included to demonstrate the technique.
