A coupling technique for non-matching finite element meshes
(Elsevier B.V., 2015-06-15)
This paper presents a novel technique for coupling non-matching finite element meshes, based on the use of special finite elements termed coupling finite elements (CFEs), which share nodes with non-matching meshes. The ...

Template-based quadrilateral meshing
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Generating quadrilateral meshes is a highly non-trivial task, as design decisions are frequently driven by specific application demands. Automatic techniques can optimize objective quality metrics, such as mesh regularity, ...
A coupled FEM-SBFEM approach for soil-structure-interaction analysis using non-matching meshes at the near-field far-field interface
(Elsevier, 2019-06)
Nowadays numerical simulation of soil structure interaction (SSI)is applied to different problems, such as the construction of reliable earthquake-resistant structures. To analyze SSI considering unbounded domains, a ...
A new discrete fracture approach based on the use of coupling finite elements for modeling fluid transport in naturally fractured porous media
(2021-12-01)
The presence of natural fractures in a porous medium strongly influences the fluid flow path. The complex geometric characteristics of the fracture network create preferential channels that change the permeability of the ...
Aplicação de elementos finitos de acoplamento para a modelagem explícita dos efeitos de fraturas naturais em análises de fluxo em meios porosos saturados
(Universidade Estadual Paulista (Unesp), 2021-04-21)
Os diferentes níveis de escalas entre o reservatório (matriz porosa) e as fraturas (ou mesmo feições cársticas) constituem um problema bastante desafiador à indústria do petróleo. Com base nisso, este trabalho apresenta ...
Modeling the hydrodynamic behavior of fractures and barriers in porous media using coupling finite elements
(2022-01-01)
Fractures, vugs and barriers are geological structures that strongly affect the fluid flow in porous media. While the first two lead to the formation of preferential flow paths, the latter blocks the flow and induces ...
Computational modeling of 2D frictional contact problems based on the use of coupling finite elements and combined contact/friction damage constitutive model
(2022-02-01)
This work proposes a new approach to describe 2D frictional contact problems based on the use of coupling finite elements (CFEs) and a combined contact/friction damage constitutive model. This technique is able to establish ...
Data-aware 3D partitioning for generic shape retrieval
(2013)
In this paper, we present a new approach for generic 3D shape retrieval based on a mesh partitioning scheme. Our method combines a mesh global description and mesh partition descriptions to represent a 3D shape. The ...
