Abstract
The design process of a mesh generation tool for automatic remeshing of hexahedral element meshes is sho~ as well as its application to the field of simulating metal forming processes. Automatic hexahedral remeshing is very important allowing an economic analyses of processes with large deformation. Although the industry demands robust tools for automatic hexahedral remeshing, previously there were no tools available that have been accepted by the commercial users. An attempt has been made to close that gap. Besides the selection of the most promising meshing technique the octree-based meshing technique solutions for other problems that are related to automatic hexahedral remeshing are discussed. Their implementation is presented as well as examples of industrial applications.
