A Comparison of Inexact Newton and Coordinate Descent Mesh Optimization Techniques
We compare inexact Newton and coordinate descent methods for optimizing the quality of a mesh by repositioning the vertices, where quality is measured by the harmonic mean of the ...

Inverse Pre-Deformation of Finite Element Mesh for Large Deformation Analysis
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...

Non-Replicating Indexing for Out-Of-Core Processing of Semi-Regular Triangular Surface Meshes
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...

Mesh Smoothing Schemes Based on Optimal Delaunay Triangulations
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...

Smoothing and Adaptive Redistribution for Grids with Irregular Valence and Hanging Nodes
We describe some extensions to the grid smoothing scheme described in [1, 2] that deal with the following issues: 1) the clustering effect of changing valence in an unstructured ...

Extracting Hexahedral Mesh Structures from Balanced Linear Octrees
Generating large 3D unstructured meshes with over 1 billion elements has been a challenging task. Fortunately, for a large class of applications with relatively simple geometries,...
