Algebraic Mesh Quality Metrics [PDF]
SIAM Journal on Scientific Computing, 2001 The author builds a mathematical theory of quality metrics for structured and unstructured meshes. A mesh has elements and nodes. An element quality metric is a scalar function of node positions that measures some geometric property of the element with the given nodes.

Generation of curved high-order meshes with optimal quality and geometric accuracy [PDF]
, 2016 We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric L2-disparity measure into a single objective function.

Anisotropic mesh quality measures and adaptation for polygonal meshes [PDF]
Journal of Computational Physics, 2020 Anisotropic mesh quality measures and anisotropic mesh adaptation are studied for polygonal meshes. Three sets of alignment and equidistribution measures are developed, one based on least squares fitting, one based on generalized barycentric mapping, and the other based on singular value decomposition of edge matrices.

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

Tetrahedral mesh improvement using moving mesh smoothing, lazy searching flips, and RBF surface reconstruction [PDF]
, 2017 Given a tetrahedral mesh and objective functionals measuring the mesh quality which take into account the shape, size, and orientation of the mesh elements, our aim is to improve the mesh quality as much as possible.

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.

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.

An efficient method to improve the quality of tetrahedron mesh with MFRC
Scientific Reports, 2021 In this paper, we proposed a novel operation to reconstruction tetrahedrons within a certain region, which we call MFRC (Multi-face reconstruction). During the existing tetrahedral mesh improvement methods, the flip operation is one of the very important
