Mesh evaluation method for shell elements using graph convolutional network
Nihon Kikai Gakkai ronbunshu, 2023 Finite element mesh quality, which affects analysis accuracy and computational cost, is usually determined based on the designer's experience. In this study, we propose a GCN (Graph Convolutional network)-based method for evaluating the quality of ...

Building Geometry Simplification for Improving Mesh Quality of Numerical Analysis Model
Applied Sciences, 2020 Numerical analysis, especially the finite volume method (FVM), is one of the primary approaches employed when evaluating a building environment. A complicated geometry can degrade the mesh quality, leading to numerical diffusions and errors.

Quality meshing for polyhedra with small angles [PDF]
Proceedings of the twentieth annual symposium on Computational geometry, 2004 We present an algorithm to compute a Delaunay mesh conforming to a polyhedron possibly with small input angles. The radius-edge ratio of most output tetrahedra are bounded by a constant, except possibly those that are provably close to small angles.

A Survey of Indicators for Mesh Quality Assessment
Computer Graphics Forum, 2023 AbstractWe analyze the joint efforts made by the geometry processing and the numerical analysis communities in the last decades to define and measure the concept of “mesh quality”. Researchers have been striving to determine how, and how much, the accuracy of a numerical simulation or a scientific computation (e.g., rendering, printing, modeling ...

Quality Mesh Generation in Higher Dimensions [PDF]
SIAM Journal on Computing, 2000 Triangulation of a \(d\)-dimensional region is considered. The mesh generation algorithm, called QMG, is a quadtree-based algorithm that can triangulate any polyhedral region including nonconvex regions with holes. The algorithm guarantees a bounded aspect ratio triangulation if the input domain contains no sharp angles.

Improved GETMe by adaptive mesh smoothing
Computer Assisted Methods in Engineering and Science, 2017 Mesh smoothing improves mesh quality by node relocation without altering mesh topology. Such methods play a vital role in finite element mesh improvement with a direct consequence on the quality of the discretized solution.

A Triangle Mesh Standardization Method Based on Particle Swarm Optimization. [PDF]
PLoS ONE, 2016 To enhance the triangle quality of a reconstructed triangle mesh, a novel triangle mesh standardization method based on particle swarm optimization (PSO) is proposed. First, each vertex of the mesh and its first order vertices are fitted to a cubic curve

As-equilateral-as-possible surface remeshing
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 Surface remeshing aims to produce a high-quality mesh from a given input mesh. In this paper, we present a practical approach to isotropic surface remeshing of triangular meshes in an as-equilateral-as-possible (AEAP) manner.
