Differential mesh generation [PDF]
SEG Technical Program Expanded Abstracts 2006, 2006 This paper examines a differential gridding method for generating computational meshes appropriate for solving partial differential equations. Differential methods pose mesh generation as an elliptical boundary value problem within a framework of differential geometry. Generalized Laplacian operators are used to propagate the known coordinate values on

Finite element mesh generation and adaptive meshing
Progress in Structural Engineering and Materials, 2002AbstractThis review paper gives a detailed account of the development of mesh generation techniques on planar regions, over curved surfaces and within volumes for the past years. Emphasis will be on the generation of the unstructured meshes for purpose of complex industrial applications and adaptive refinement finite element analysis.

IETE Journal of Education, 2012
AbstractMesh analysis and the graph theoretic current method are widely taught in circuit theory courses at under graduate level. In this paper a new loop current method is proposed which combines both of them into one. The method uses the concept of a spanning planar sub graph (plang).

Adaptive triangular mesh generation [PDF]
AIAA Journal, 1984 A general adaptive grid algorithm is developed on triangular grids. The adaptivity is provided by a combination of node addition, dynamic node connectivity and a simple node movement strategy. While the local restructuring process and the node addition mechanism take place in the physical plane, the nodes are displaced on a monitor surface, constructed

CRM: Single Image to 3D Textured Mesh with Convolutional Reconstruction Model
European Conference on Computer VisionFeed-forward 3D generative models like the Large Reconstruction Model (LRM) have demonstrated exceptional generation speed. However, the transformer-based methods do not leverage the geometric priors of the triplane component in their architecture, often

Adaptivity and mesh generation
International Journal for Numerical Methods in Engineering, 1991AbstractThe objective of achieving economically finite element solutions of specified accuracy is now within reach. The importance of this objective is finally recognized by commercial code originators and efforts directed at automating the process are meeting with success.Three essential ingredients are here necessary.

A new strategy for unstructured mesh generation [PDF]
Fluids 2000 Conference and Exhibit, 2000 A novel strategy, which includes the statements of the no-cavity and nonoverlapping conditions and a mesh generation approach, is presented to create unstructured triangular and tetrahedral meshes. For this strategy, the no-cavity and nonoverlapping conditions provide the theoretical basis for the mesh-generation procedure.
