Exact asymptotics of the uniform error of interpolation by multilinear splines [PDF]
The question of adaptive mesh generation for approximation by splines has been studied for a number of years by various authors. The results have numerous applications in computational and discrete geometry, computer aided geometric design, finite ...

We study several versions of the problem of generating triangular meshes for finite element methods. We show how to triangulate a planar point set or polygonally bounded domain with triangles of bounded aspect ratio; how to triangulate a planar point set with triangles having no obtuse angles; how to triangulate a point set in arbitrary dimension with ...

Preconditioning the Quad Dominant Mesh Generator for Ship Structural Analysis
This paper presents an algorithm for the fully automatic mesh generation for the finite element analysis of ships and offshore structures. The quality requirements on the mesh generator are imposed by the acceptance criteria of the classification ...

Analysis of Hydrostatic Bearings Based on a Unstructured Meshing Scheme and Turbulence Model
Guideway hydrostatic bearings with the function of supporting and moving loads are a key component of ultra-precision heavy-duty machine tools. Because the dimension difference between the oil gap and the overall structure is great, it is difficult to ...

Improving mesh generation in finite element analysis for functional morphology approaches
Finite Element Analysis (FEA) is a powerful tool for functional morphology purposes. The accuracy of the final results depends on the mesh generation and the quality of the mesh.

Performance and Optimization Abstractions for Large Scale Heterogeneous Systems in the Cactus/Chemora Framework [PDF]
We describe a set of lower-level abstractions to improve performance on modern large scale heterogeneous systems. These provide portable access to system- and hardware-dependent features, automatically apply dynamic optimizations at run time, and target ...

New Method to Recover Activation Energy: Application to Copper Oxidation
The calculation of the activation energy helps to understand and to identify the underlying phenomenon of oxidation. We propose a new method without any a priori hypothesis on the oxidation law, to retrieve the activation energy of partially and totally ...

Voxel2Mesh: 3D Mesh Model Generation from Volumetric Data [PDF]
CNN-based volumetric methods that label individual voxels now dominate the field of biomedical segmentation. However, 3D surface representations are often required for proper analysis.

Shrinking tube mesh: combined mesh generation and smoothing for pathologic vessels
We present a mesh generation algorithm which is able to produce smooth meshes from point clouds derived from histological slices. In this work, the shrinking tube mesh generation is used on histologic images depicting pathologic vessels.
