• We developed a mesh morphing technique, which can be used to change the shape of existing analytical mesh models, and generated a mesh model for a new shape by morphing the mesh model for the previous one. Therefore, our method is suitable to use for analysis during the early stage of design because it reduces the amount of time required to generate analytical mesh models. However, when the deformation measure of mesh morphing is large, mesh was distorted. We developed the mesh quality improvement technique for solving this problem. Compared with conventional methods, our method improves the poor quality elements by mesh regeneration of deleted space of poor quality elements. And our method establishes objective mesh quality from original mesh data. By these methods, deteriorated elements quality by mesh morphing can be improved. We demonstrated the effectiveness of our method by applying it to bracket model and oil pump housing model.
