Measuring Mesh Qualities and Application to Variational Mesh Adaptation [PDF]

open access: yesSIAM Journal on Scientific Computing, 2005
Summary: The mesh assessment problem is investigated in this paper by taking into account the shape and size of elements and the solution behavior. Three elementwise mesh quality measures characterizing the shape, alignment, and adaptation features of elements are introduced according to the estimates of interpolation error developed on a general mesh.

Surface reconstruction with spherical harmonics and its application for single particle crushing simulations

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2022
Particle morphology has great influence on mechanical behaviour and hydro/thermal/electrical conductivities of granular materials. Surface reconstruction and mesh generation are critical to consider realistic particle shapes in various computational ...

An Alternating Mesh Quality Metric Scheme for Efficient Mesh Quality Improvement

open access: yesProcedia Computer Science, 2011
AbstractIn the numerical solution of partial differential equations (PDEs), high-quality meshes are crucial for the stability, accuracy, and convergence of the associated PDE solver. Mesh quality improvement is often performed to improve the quality of meshes before use in numerical solution of the PDE.

Three-dimensional CFD simulations with large displacement of the geometries using a connectivity-change moving mesh approach [PDF]

open access: yes, 2018
This paper deals with three-dimensional (3D) numerical simulations involving 3D moving geometries with large displacements on unstructured meshes. Such simulations are of great value to industry, but remain very time-consuming.

Hiatoplasty with crura buttressing versus hiatoplasty alone during laparoscopic sleeve gastrectomy [PDF]

open access: yes, 2017
Introduction. In obese patients with hiatal hernia (HH), laparoscopic sleeve gastrectomy (LSG) with cruroplasty is an option but use of prosthetic mesh crura reinforcement is debated.
