Multiblock Mesh Refinement by Adding Mesh Singularities [PDF]

open access: yes, 2019
Several templates for 2D and 3D structured mesh refinement are presented. The templates have the property that the minimum number of irregular points or edges (mesh singularities) are added. For a given set of external division numbers a variety of interior meshes can be generated.

An Open-Source Processing Pipeline for Quad-Dominant Mesh Generation for Class-Compliant Ship Structural Analysis

open access: yesJournal of Marine Science and Engineering, 2022
We present an algorithm for the fully automatic generation of a class-compliant mesh for ship structural analysis. Our algorithm is implemented as an end-to-end solution.

Effect of Mesh Shape and Turbulence Model on Aerodynamic Performance at NACA 4415 [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
This study uses three turbulence model variations, i.e., S - A, k - ε, and k – ω turbulence models. In addition, there are two variations of cell shape and three variations of cell number. The number of cells is 500, 5000, 50000, and 100000. Verification

Kinetic mesh refinement in 2D [PDF]

open access: yesProceedings of the twenty-seventh annual symposium on Computational geometry, 2011
We provide a kinetic data structure (KDS) to the planar kinetic mesh refinement problem, which concerns computation of meshes of continuously moving points. Our KDS computes the Delaunay triangulation of a size-optimal well-spaced superset of a set of moving points with algebraic trajectories of constant degree.

Rate-distortion performance of dual-layer motion compensation employing different mesh densities [PDF]

open access: yes, 2006
We describe a dual layer algorithm for mesh-based motion estimation. The proposed algorithm, employing meshes at different scales, aims to improve the rate-distortion performance at fixed bit rates.
