An Automatic Hexahedral Mesh Generation System with Feature Line Extraction Technique

Abstract

A technique for generating automatic hexahedral mesh in a complex solid model was developed. This technique can automate the interactive operations (such as model editing) that are carried out as a pretreatment for hexahedral-mesh generation. Consequently, in our tests, the time taken by these interactive operations was significantly shortened, and high-speed generation of a hexahedral mesh was thus possible. The technique was applied to generation of a hexahedral mesh of an engine-block model. It was confirmed that the mesh generation time is shortened to one tenth of the conventional method's time.
