On a robust boundary layer mesh generation process
, 2017A closed advancing-layer method for generating high-aspect-ratio elements in the boundary layer (BL) region is presented. This approach provides an answer to the mesh generation robustness issue as it starts from an existing valid mesh and always ...

Simultaneous mesh generation and partitioning for Delaunay meshes
Mathematics and Computers in Simulation, 2000In this paper, we present a new approach for the parallel generation and partitioning of unstructured 3D Delaunay meshes. The new approach couples the mesh generation and partitioning problems into a single optimization problem. Traditionally, these two problems are solved separately, first generating the mesh (usually sequentially) and then ...

MeshLRM: Large Reconstruction Model for High-Quality Mesh
arXiv.orgWe propose MeshLRM, a novel LRM-based approach that can reconstruct a high-quality mesh from merely four input images in less than one second. Different from previous large reconstruction models (LRMs) that focus on NeRF-based reconstruction, MeshLRM ...

Telescopic Approach for Extreme-Scale Parallel Mesh Generation for CFD Applications
, 2016We address two challenges related to Extreme-scale Mesh Generation Environments: (1) Design a multilayered algorithmic and software framework for 3D tetrahedral parallel mesh generation using state-of-theart functionality supported by our telescopic ...

Graded mesh generation and transformation
Finite Elements in Analysis and Design, 1994A simple and fast method to generate graded quadrilateral mesh has been developed. This method guarantees the generation of quadrilateral mesh once the triangular base mesh has been generated. The gradation of triangular mesh is self controlled for the internal nodes in the generation process, the boundary nodes gradiation is controlled by assigning ...

The efficient parallelisation of the finite element method is based on non-overlapping partitioning of the computational domain into an appropriate number of subdaomins. The problem size required for efficient application of parallel solution techniques is considerably large.

SF3D: Stable Fast 3D Mesh Reconstruction with UV-unwrapping and Illumination Disentanglement
arXiv.orgWe present SF3D, a novel method for rapid and high-quality textured object mesh reconstruction from a single image in just 0.5 seconds. Unlike most existing approaches, SF3D is explicitly trained for mesh generation, incorporating a fast UV unwrapping ...
