Anisotropic Delaunay Mesh Generation [PDF]

open access: yesSIAM Journal on Computing, 2015
Summary: Anisotropic meshes are triangulations of a given domain in the plane or in higher dimensions, with elements elongated along prescribed directions. Anisotropic triangulations are known to be well suited for interpolation of functions or solving PDEs.

An ANN-based advancing double-front method for automatic isotropic triangle generation

open access: yesScientific Reports, 2022
The advancing front method (AFM) is one of the widely used unstructured grid generation techniques. However, the efficiency is relatively low because only one cell is generated in the advancing procedure.

Cover interpolation functions and h-enrichment in finite element method [PDF]

open access: yesNumerical Methods in Civil Engineering, 2017
This paper presents a method to improve the generation of meshes and the accuracy of numerical solutions of elasticity problems, in which two techniques of h-refinement and enrichment are used by interpolation cover functions.

Effects of Mesh Generation on Modelling Aluminium Anode Baking Furnaces

open access: yesFluids, 2021
Anode baking is critical in carbon anode production for aluminium extraction. Operational and geometrical parameters have a direct impact on the performance of anode baking furnaces (ABF), and hence on the resulting anode quality.

Reconstruction of tree branching structures from UAV-LiDAR data

open access: yesFrontiers in Environmental Science, 2022
The reconstruction of tree branching structures is a longstanding problem in Computer Graphics which has been studied over several data sources, from photogrammetry point clouds to Terrestrial and Aerial Laser Imaging Detection and Ranging technology ...

Application of Novel Hybrid Mesh Generation Methodologies for Improved Unstructured CFD Simulations [PDF]

open access: yes, 2010
On the basis of the DLR contribution to DPW4, a procedure to produce an unstructured grid-convergence family as self-similar as possible is documented, with a specific procedure for steering the nearfield, advancing-layer process.

Numerical Simulation Analysis of Cavitation Performance of Tandem Propeller [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
The steady non cavitation hydrodynamic characteristics of CLB4-55-1 tandem propeller and the steady cavitation flows of NACA66 hydrofoil are numerically studied firstly based on the RANS equations of homogeneous multiphase using CFD theory, combined with

New Quality Measures for Quadrilaterals and New Discrete Functionals for Grid Generation

open access: yesMathematical and Computational Applications, 2023
In this paper, we review some grid quality metrics and define some new quality measures for quadrilateral elements. The curved elements are not discussed.

Direct modification of semanticaly-enriched finite element meshes [PDF]

open access: yes, 2010
Behaviour analysis loop is largely performed on virtual product model before its physical manufacturing. The last avoids high expenses in terms of money and time spent on intermediate manufacturing.

Numerical Study of Photoacoustic Pressure for Cancer Therapy

open access: yesApplied Sciences, 2016
A commonly used therapy for cancer is based on the necrosis of cells induced by heating through the illumination of nanoparticles embedded in cells. Recently, the photoacoustic pressure shock induced by the illumination pulse was proved and this points ...
