Parallel mesh generation

1997
The efficient parallelisation of the finite element method is based on non-overlapping partitioning of the computational domain into an appropriate number of subdaomins. The problem size required for efficient application of parallel solution techniques is considerably large.

Hexahedral mesh generation constraints

Engineering with Computers, 2008
For finite element analyses within highly elastic and plastic structural domains, hexahedral meshes have historically offered some benefits over tetrahedral finite element meshes in terms of reduced error, smaller element counts, and improved reliability.

A Generic Algorithm for Mesh Optimisation

The International Journal of Advanced Manufacturing Technology, 2001
The method presented in this paper optimises a given triangular mesh surface with respect to prescribed criteria to obtain a unit surface mesh. Two criteria are defined to guide the mesh optimisation scheme. In the procedure, we use three optimisation operators (edge split, edge collapse, and edge swap), and a local spherical surface is defined to ...

3D Mesh Generation in Geocomputing

2009
Mesh generation has been widely used in engineering computing, but seems to be relatively "new" for geoscience community. This paper firstly lists such relevant progresses of mesh generation for the engineering computing and then discusses the possibility for applying/ extending them to geoscience computing (i.e. geocomputing).

Linear Sources for Mesh Generation

SIAM Journal on Scientific Computing, 2013
Sources offer a convenient way to prescribe a size distribution in space. For each newly created mesh point, the mesh generator queries the local size distribution, either to create a new point or element, depending on the underlying mesh generation method, to smooth the mesh, or to get a local relevant length scale.

Mesh generation

2002
Abstract In the finite element approach to problems in greater than one dimension we are immediately faced with the complex issue of discretization of the physical domain. In this chapter we shall consider the essentials of 2D mesh generation.

Adaptive sampling and mesh generation

Computer-Aided Design, 1995
The aim of this paper is to present an algorithm for sampling a continuous surface into discrete points while best preserving information on its shape. Given the boundary conditions, the solution is determined entirely by the surface shape function and the definition of neighbourhood.

Simplification Algorithm for General Meshes

2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012
A new mesh simplification framework based on the i®simplex collapse', which can produce approximations of simplified complexes of any type of meshes embedded in three dimensional Euclidean spaces, such as triangular meshes, quadrangular meshes, tetrahedral meshes, hexahedral meshes, and mixed complexes was presented in this paper.

The QMESH mesh generation package

Proceedings of the SIGNUM meeting on Software for partial differential equations -, 1975
A package of five programs centering around the highly flexible, powerful, two-dimensional mesh generation program, QMESH, is presented. Together, the five programs provide a tool for generation, bandwidth minimization and display of meshes with Q4 or Q8 elements. The package's primary purpose is generation of input for finite element analysis programs.
