GPU smoothing of quad meshes [PDF]
We present a fast algorithm for converting quad meshes on the GPU to smooth surfaces. Meshes with 12,000 input quads, of which 60% have one or more non-4-valent vertices, are converted, evaluated and rendered with 9times9 resolution per quad at 50 frames per second.

On the mesh nonsingularity of the moving mesh PDE method [PDF]
The moving mesh PDE (MMPDE) method for variational mesh generation and adaptation is studied theoretically at the discrete level, in particular the nonsingularity of the obtained meshes.

Laplacian mesh smoothing with bilateral weights for characterization of freeform surfaces
Freeform surfaces are widely used in advanced manufacturing due to their versatility, yet their complex geometries make characterization challenging. To do a surface texture analysis, it is often necessary to first remove the form of the surface.

An ANN-based advancing double-front method for automatic isotropic triangle generation
The advancing front method (AFM) is one of the widely used unstructured grid generation techniques. However, the efficiency is relatively low because only one cell is generated in the advancing procedure.

Smoothing properties of two-color distributive relaxation for solving a two-dimensional (2D) Stokes flow by multigrid method are theoretically investigated by using the local Fourier analysis (LFA) method.

High-Frequency Voronoi Noise Reduced by Smoothed Mesh Motion [PDF]
We describe a technique for improving the performance of hydrodynamics codes which employ a moving Voronoi mesh. Currently, such codes are susceptible to high-frequency noise produced by rapid adjustments in the grid topology on the smallest scales.

Parallel Feature-Preserving Mesh Smoothing [PDF]
We present a parallel approach for optimizing surface meshes by redistributing vertices on a feature-aware higher-order reconstruction of a triangulated surface. Our method is based on a novel extension of the fundamental quadric, called the medial quadric.

Discrete Fourier analysis of multigrid algorithms [PDF]
The main topic of this report is a detailed discussion of the discrete Fourier multilevel analysis of multigrid algorithms. First, a brief overview of multigrid methods is given for discretizations of both linear and nonlinear partial differential ...
