Two‐dimensional adaptive quadrilateral mesh generation

Communications in Numerical Methods in Engineering, 1994
AbstractIn the paper we address the problem of 2D adaptive quadrilateral mesh generation by using the variational principles. We first find the variational integral which generates the known grid system of curve‐by‐curve error equidistributions. We then use the same intergral to generate a new adaptive grid system which is superior to the known system ...

Parallel Unstructured Quadrilateral Mesh Generation

2005
In this paper we present our efforts to parallelize an unstructured quadrilateral mesh generator. Its serial version is based on the divider-and-conquer idea, and mainly includes two stages, i.e. geometry decomposition and mesh generation. Both stages are parallelized separately.

Mesh enrichment against mesh regeneration using quadrilateral elements

Communications in Numerical Methods in Engineering, 1993
AbstractAn adaptive refinement procedure using a new automatic quadrilateral element mesh generator is presented. The performance of the adaptive procedure in achieving a given accuracy with different mesh refinement strategies is compared. It is found that when using bilinear or biquadratic quadrilateral elements refinement strategies of both mesh ...

Discrete differential geometry: The nonplanar quadrilateral mesh

Physical Review E, 2012
We consider the problem of constructing a discrete differential geometry defined on nonplanar quadrilateral meshes. Physical models on discrete nonflat spaces are of inherent interest, as well as being used in applications such as computation for electromagnetism, fluid mechanics, and image analysis.

High‐order residual distribution schemes on quadrilateral meshes

International Journal for Numerical Methods in Fluids, 2007
AbstractThis article deals with the latest development in the construction of monotone high‐order residual distribution schemes (RDS) on quadrilateral meshes. In the first part we give some generalities about the way upwind high‐order RDS is designed. In the second part, some standard schemes are described.

Discrete ordinates scheme for quadrilateral meshes

Annals of Nuclear Energy, 1988
Abstract A simple extension of the discrete ordinates method for solving the transport equation with quadrilateral meshes in X - Y and R - Z geometry is described. Numerical results of some benchmark problems are presented for showing the adequacy of the modified scheme.
