Superconvergence of the Velocity in Mimetic Finite Difference Methods on Quadrilaterals [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2005
Summary: Superconvergence of the velocity is established for mimetic finite difference approximations of second-order elliptic problems over \(h^2\)-uniform quadrilateral meshes. The superconvergence holds for a full tensor coefficient. The analysis exploits a relation between mimetic finite differences and mixed finite element methods via a special ...

Mimetic Finite Difference methods for Hamiltonian wave equations in 2D

open access: yesComputers & Mathematics with Applications, 2016
In this paper we consider the numerical solution of the Hamiltonian wave equation in two spatial dimension. We use the Mimetic Finite Difference (MFD) method to approximate the continuous problem combined with a symplectic integration in time to ...

Convergence of the Mimetic Finite Difference Method for Diffusion Problems on Polyhedral Meshes [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2005
The stability and convergence properties of the mimetic finite difference method for diffusion-type problems on polyhedral meshes are analyzed. The optimal convergence rates for the scalar and vector variables in the mixed formulation of the problem are proved.

Local flux mimetic finite difference methods [PDF]

open access: yesNumerische Mathematik, 2008
The authors use a MFPA-type construction to develop new cell-centered discretization methods on polyhedral meshes for diffusion problems with full tensor coefficients. Under a few constructive assumptions they prove first-order convergence for both the velocity and the pressure variables, as well as second-order superconvergence for the pressure ...

A mortar mimetic finite difference method on non-matching grids [PDF]

open access: yesNumerische Mathematik, 2005
This paper deals with the mimetic finite difference (MFD) method on nonmatching multiblock grids for second-order linear elliptic equation with Dirichlet boundary conditions. The authors establish a relation between the mortar MFD method and mortar mixed finite element methods.

The curved mimetic finite difference method: Allowing grids with curved faces

open access: yesJournal of Computational Physics, 2023
We present a new mimetic finite difference method for diffusion problems that converges on grids with \textit{curved} (i.e., non-planar) faces. Crucially, it gives a symmetric discrete problem that uses only one discrete unknown per curved face. The principle at the core of our construction is to abandon the standard definition of local consistency of ...

The mimetic finite difference method for the Landau–Lifshitz equation [PDF]

open access: yesJournal of Computational Physics, 2017
The Landau-Lifshitz equation describes the dynamics of the magnetization inside ferromagnetic materials. This equation is highly nonlinear and has a non-convex constraint (the magnitude of the magnetization is constant) which pose interesting challenges in developing numerical methods.
