Abstract
This paper proposes an algorithm for generating a mesh that is similar to a given reference mesh in particular features. In the design process, similar kinds of meshes are generated for the same shape or similar shapes repeatedly. Once a mesh having the desired features is obtained, our algorithm can generate the succeeding meshes efficiently by imitating a selected set of features of the reference mesh. The algorithm (1) captures the significant features (element size, element orientation, and anisotropy) of the reference mesh in the form of a tensor field, (2) transforms the tensor field to modify the features, and (3) generates a refined mesh according to the modified tensor field. The results show that the generated mesh globally preserves specified features of the reference mesh. A mesh having the desired qualities will be easily obtained with just a few local mesh modifications.
