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.

Automated Conversion of 2D Triangular Mesh into Quadrilateral Mesh

1995
In some types of FEM analysis, such as automobile crash simulation and sheet-metal forming simulation, quadrilateral meshes are preferred to triangular meshes because of their superior solution accuracy. Most commercial or in-house quadrilateral mesh generators today employ mapping methods, in which the user must decompose the geometric domain manually

Refining Quadrilateral and Brick Element Meshes

1995
We consider the problem of refining unstructured quadrilateral and brick element meshes. We present an algorithm which is a generalization of an algorithm developed by Cheng et. al. for structured quadrilateral element meshes. The problem is solved for the two-dimensional case.
