Description

We developed a mesh morphing technique that can be used to change the shape of existing analytical mesh models, and we generated a mesh model for a new shape by morphing the mesh model for the previous one. 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 the feature in the original mesh by using a Boolean technique and a mesh improvement technique. Our technique can process the addition and deletion of a feature in a 100000-element mesh model in about 1 minute. Moreover, this technique can generate high-quality meshes that ensure the element stretch is more than 0.1. We demonstrated the effectiveness of our technique by applying it to models of two different kinds of engine blocks.
