A mixed discretization of elliptic problems on polyhedra using anisotropic hybrid meshes
(Springer, 2019-06)
A Virtual Element Method is introduced for the mixed approximation of a simple model problem for the Laplace operator on a polyhedron. The method is fully analysed when the meshes are made up of triangular right prisms, ...
An anisotropic a priori error analysis for a convection-dominated diffusion problem using the HDG method
(Elsevier Science SA, 2019-03-01)
This paper deals with the a priori error analysis for a convection-dominated diffusion 2D problem, when applying the HDG method on a family of anisotropic triangulations. It is known that in this case, boundary or interior ...
Anisotropic mesh refinement in polyhedral domains: error estimates with data in L 2 (Ω)
(EDP Sciences, 2014-08)
The paper is concerned with the finite element solution of the Poisson equation with homogeneous Dirichlet boundary condition in a three-dimensional domain. Anisotropic, graded meshes from a former paper are reused for ...
Spatial patterns of magnetic susceptibility optimized by anisotropic correction in different Alisols in southern Amazonas, Brazil
(2022-04-01)
Changes in primary cover for agricultural crops in Amazonas region influence the phenomenon of spatial variability in soil properties. This phenomenon is still studied assuming that the spatial data is isotropic, but does ...
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 ...
