Real-space mesh techniques in density-functional theory [PDF]
Reviews of Modern Physics, 2000 This review discusses progress in efficient solvers which have as their foundation a representation in real space, either through finite-difference or finite-element formulations. The relationship of real-space approaches to linear-scaling electrostatics and electronic structure methods is first discussed.

VoroCrust: Voronoi Meshing Without Clipping
, 2020 Polyhedral meshes are increasingly becoming an attractive option with particular advantages over traditional meshes for certain applications. What has been missing is a robust polyhedral meshing algorithm that can handle broad classes of domains ...

Well-Centered Triangulation [PDF]
, 2008 Meshes composed of well-centered simplices have nice orthogonal dual meshes (the dual Voronoi diagram). This is useful for certain numerical algorithms that prefer such primal-dual mesh pairs.

Resistive-force theory for mesh-like superhydrophobic surfaces [PDF]
Physical Review Fluids, 2018 A common realization of superhydrophobic surfaces makes use of a mesh-like geometry, where pockets of air are trapped in a periodic array of holes in a no-slip solid substrate. We consider the small-solid-fraction limit where the ribs of the mesh are narrow.

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]
, 2019 A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic
