We developed technique for automatically generating a hexahedral mesh of a complex solid model. This technique can automatically convert a solid model to a feature shape model that consists of the feature lines necessary for generating hexahedral mesh. We have thus automated the interactive operations (such as model editing) that are carried out as a pretreatment for hexahedral mesh generation, and significantly shortened the time taken for these interactive operations. Furthermore, a technique for generating high quality hexahedral mesh that faithfully expressed the corner part of a solid model was developed. We applied these developed techniques to the generation of the hexahedral mesh of an engine block model, and confirmed that the mesh generation time is shortened to one eighth that of the conventional method.
