Advanced calculation due to progress in computing power and the development of mesh-generating capabilities for analyzing structures have led to the need for a pre-processor that can generate an optimal mesh quickly and accurately. Tetrahedron and hexahedron meshes are generally used in structural analysis ; the former is very adaptable to various structural configurations, and the latter calculates accurate results. Using these features, we have developed an automatic mesh pre-processor that can generate a hexahedron mesh for the part requiring precise results and tetrahedron mesh for the remaining part. To conserve displacement compatibility, a pyramidal mesh is used for the interface between these two meshes. Simulation showed that this method works well for finite-element-method modeling of holed-plate extensions and gearings.
