Adaptive triangular-quadrilateral mesh generation [PDF]
International Journal for Numerical Methods in Engineering, 1998 The authors propose an automatic triangular to quadrilateral mesh conversion adaption scheme and introduce a new optimal vertex smoothing procedure. Some numerical results, academic tests and a computational fluid dynamics example show the efficiency of the proposed method.

Efficient unstructured quadrilateral mesh generation [PDF]
International Journal for Numerical Methods in Engineering, 2000 This work is devoted to the description of an algorithm for automatic quadrilateral mesh generation. The technique is based on a recursive decomposition of the domain into quadrilateral elements. This automatically generates meshes composed entirely by quadrilaterals over complex geometries (there is no need for a previous step where triangles are ...

Quadrilateral mesh simplification [PDF]
ACM Transactions on Graphics, 2008 We introduce a simplification algorithm for meshes composed of quadrilateral elements. It is reminiscent of edge-collapse based methods for triangle meshes, but takes a novel approach to the challenging problem of maintaining the quadrilateral connectivity during level-of-detail creation.

A parallel edge orientation algorithm for quadrilateral meshes [PDF]
, 2015 One approach to achieving correct finite element assembly is to ensure that the local orientation of facets relative to each cell in the mesh is consistent with the global orientation of that facet. Rognes et al.

The Virtual Element Method for the Dam Foundation With Joint
Frontiers in Earth Science, 2022 The contact is a typical non-linear problem that exists in various projects. For traditional three-node triangular mesh and four-node quadrilateral mesh, the accuracy and convergence of the calculation results are affected by the quality of the mesh. The

Rectangular/Triangular Hybrid Mesh Generation for Electromagnetic Analysis of Integrated Circuits
IEEE Access, 2023 This paper presents a novel hybrid mesh generation algorithm for electromagnetic analysis of radio frequency integrated circuits (RFIC) using the method of moments (MoM). Due to its characteristics, MoM prefers rectangular or triangular meshes instead of
