A Mixed Finite Volume Element Method for Time-Fractional Reaction-Diffusion Equations on Triangular Grids

open access: yesMathematics, 2019
In this article, the time-fractional reaction-diffusion equations are solved by using a mixed finite volume element (MFVE) method and the L 1 -formula of approximating the Caputo fractional derivative.

Mixed Finite Volume Element Method for Vibration Equations of Beam with Structural Damping

open access: yesAmerican Journal of Computational Mathematics, 2021
In this paper, for the initial and boundary value problem of beams with structural damping, by introducing intermediate variables, the original fourth-order problem is transformed into second-order partial differential equations, and the mixed finite volume element scheme is constructed, and the existence, uniqueness and convergence of the scheme ...

A residual based A POSTERIORI error estimator for an augmented mixed finite element method in linear elasticity [PDF]

open access: yes, 2005
In this paper we develop a residual based a posteriori error analysis for an augmented mixed finite element method applied to the problem of linear elasticity in the plane. More precisely, we derive a reliable and efficient a posteriori error estimator

A two-level enriched finite element method for a mixed problem [PDF]

open access: yes, 2011
The simplest pair of spaces is made inf-sup stable for the mixed form of the Darcy equation. The key ingredient is to enhance the finite element spaces inside a Petrov-Galerkin framework with functions satisfying element-wise local Darcy problems with ...

A control volume-based finite element method for plane micropolar elasticity [PDF]

open access: yes, 2008
This paper describes the development of a numerical procedure for predicting deformations and stresses in a loaded two-dimensional membrane exhibiting micropolar or Cosserat constitutive behaviour. The procedure employs a conventional finite element (FE)

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]

open access: yes, 2013
Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

DOLFIN: Automated Finite Element Computing [PDF]

open access: yes, 2009
We describe here a library aimed at automating the solution of partial differential equations using the finite element method. By employing novel techniques for automated code generation, the library combines a high level of expressiveness with efficient

The finite-volume method in computational rheology [PDF]

open access: yes, 2012
The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

Application of M3GM in a Petroleum Reservoir Simulation [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
Reservoir formations exhibit a wide range of heterogeneity from micro to macro scales. A simulation that involves all of these data is highly time consuming or almost impossible; hence, a new method is needed to meet the computational cost. Moreover, the
