Optimization of a triangular mesh
Computers & Structures, 1991Abstract This paper describes a scheme for finite element mesh generation of a multiply connected, non-convex polygon. The scheme combines a non-random node generation technique and the Delaunay triangulation method for element generation to yield a mesh with optimal shaped elements.

Composite Schemes on Triangular Meshes
2001The composite schemes are given by the global composition of several steps of Lax-Wendroff scheme followed by one step of Lax-Ftiendrichs scheme bringing sufficient diffusion to smooth out dispersive Lax-Wendroff oscilations. The composite schemes are generalized to triangular mesh by finite volume approach.

MAC Schemes on Triangular Meshes
2011We present numerical results for two generalized MAC schemes on triangular meshes, which are based on staggered meshes using the Delaunay–Voronoi duality. In the first one, the pressures are defined at the vertices of the mesh, and the discrete velocities are tangential to the edges of the triangles.

Discussion of Triangular Mesh Optimization
2012The generation of nearly-regular triangular meshes which tend towards a valence of six for most vertices is quite important in many fields, such as finite element mesh design and numerical simulations. In this paper we present a novel triangular mesh optimization method which can be divided into two main parts: reduce the degree of the vertices to ...

Image Registration Using Triangular Mesh
2004Image registration is a fundamental problem in the area of computer vision and has been extensively researched. Different image registration algorithm has its pros and cons. Unlike most of the algorithms, our approach defines a set of feature points uniformly distributed on the image. The feature points are linked up as nodes in a triangular mesh.

CIP Advection on Triangular Mesh
1995As an universal solver of compressible and incompressible fluid, CIP (Cubic Interpolated Propagation) has been proposed[1–3], and good results were obtained successfully in many application problems[4,5]. All of these were based on structured square-shaped meshes in two- and three-dimensional cases.

Multiresolution mesh processing for triangular and tetrahedral meshes
2004Technical advances in the field of 3D scanning technologies in the last years have resulted in more and more detailed three dimensional models of real world objects. Hence, the size of the models has grown enormously. Despite of increased performance of computers and graphics hardware, efficient algorithms for processing such models are required more ...
