We developed a mesh morphing technique that can be used to change the shape of existing analytical mesh models. We used it to generate a mesh model of a new shape by morphing the original mesh model. Our technique can be used for analysis during the early stages of design because it reduces the time required to generate analytical mesh models. Compared with conventional techniques, our technique adds and deletes features in the original mesh by using a Boolean technique and a mesh improvement technique. It can process the addition or deletion of a feature in a 100,000-element mesh model in about one minute. Moreover, it can generate high-quality meshes that ensure element stretch of over 0.1. We demonstrated the effectiveness of our technique by applying it to two engine block models.
