Modeling the closure behavior of natural fractures in porous media using high aspect ratio interface elements
(2021-01-01)
Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...

Analysis of a semi-augmented mixed finite element method for double-diffusive natural convection in porous media
(2022-05-15)
In this paper we study a stationary double-diffusive natural convection problem in porous media given by a Navier-Stokes/Brinkman type system, for describing the velocity and the pressure, coupled to a vector advection-diffusion ...
Plan de Manejo del Elemento Natural Destacado Sistema Espeleolacustre de Zapata
(Editora Geotech, 2007)
El Sistema Espeleolacustre de Zapata está constituido por un grupo de dolinas de disolución, alineadas geotectónicamente dentro de un mismo paquete cársico, donde se desarrollan características edafológicas, hidrológicas ...
Error estimation and h-adaptive refinement in the analysis of natural frequencies
(ELSEVIER SCIENCE BV, 2001-12-01)
This paper deals with the estimation of the discretization error and the definition of an optimum h-adaptive process in the finite element analysis of natural frequencies and modes. Consistent and lumped mass matrices are ...
First description of the female of the jumping spider Balmaceda nigrosecta Mello-Leitão (Salticidae, Dendryphantini, Marpissina)
(Pensoft Publishers, 2016-02)
The female of Balmaceda nigrosecta Mello-Leitão, 1945 is described and illustrated for the first time. In addition, this paper further illustrates the male, and provides the first known observations on the natural history ...
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 ...
