Finite Element Methods for Large-Strain Poroelasticity/Chemotaxis Models Simulating the Formation of Myocardial Oedema
(2022-07-22)
In this paper we propose a novel coupled poroelasticity-diffusion model for the formation of
extracellular oedema and infectious myocarditis valid in large deformations, manifested as an interaction between interstitial ...
A posteriori error analysis of mixed finite element methods for stress-assisted diffusion problems
(2022)
We develop the a posteriori error analysis for mixed-primal and fully-mixed finite element methods approximating the stress-assisted diffusion of solutes in elastic materials. The systems are formulated in terms of stress, ...
Aritmética para maestros: el número, su operatoria y su enseñanza
(1996)
Es un manual en el que se desarrolla, de una forma sencilla, una posible introducción del niño preescolar y escolar al campo del número y del cálculo aritmético. Se sugieren actividades que tienen una función didáctica ...
Aposteriori error estimation for an augmented mixed-primal method applied to sedimentation–consolidation systems
(2018-08-15)
In this paper we develop the aposteriorierror analysis of an augmented mixed-primal finite element method for the 2D and 3D versions of a stationary flow and transport coupled system, typically encountered in sedimentati ...
Formulation and analysis of fully-mixed methods for stress-assisted diffusion problems
(2019-03)
This paper is devoted to the mathematical and numerical analysis of a mixed-mixed PDE system describing the stress-assisted diffusion of a solute into an elastic material. The equations of elastostatics are written in mixed ...
Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)
In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ...
A posteriori error analysis of a fully-mixed formulation for the Brinkman–Darcy problem
(2017-09-05)
We develop the a posteriori error analysis for a mixed finite element method
applied to the coupling of Brinkman and Darcy equations in 3D, modelling the interaction of viscous and non-viscous flow effects across a given ...
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 ...
Analysis and mixed-primal finite element discretisations for stress-assisted diffusion problems
(2018)
We analyse the solvability of a static coupled system of PDEs describing the diffusion of a solute into an elastic material, where the process is affected by the stresses exerted in the solid. The problem is formulated in ...
