In the finite element analysis that deals with large deformation, the process usually produces distorted elements at the later stages of the analysis. These distorted elements lea...

We introduce an indexing scheme for the vertices of semi-regular meshes, based on interleaving quadtrees rooted on the edges of the base mesh. Using this indexing scheme we develo...

We present several mesh smoothing schemes based on the concept of optimal Delaunay triangulations. We define the optimal Delaunay triangulation (ODT) as the triangulation that mi...
