Convergence of a Mimetic Finite Difference Method for Static Diffusion Equation [PDF]
The numerical solution of partial differential equations with finite differences mimetic methods that satisfy properties of the continuum differential operators and mimic discrete versions of appropriate integral identities is more likely to produce ...

Physics-Capturing Discretizations for Spectral Wind-Wave Models
This paper discusses the discretization methods that have been commonly employed to solve the wave action balance equation, and that have gained a renewed interest with the widespread use of unstructured grids for third-generation spectral wind-wave ...

A Finite-Element Framework for a Mimetic Finite-Difference Discretization of Maxwell's Equations [PDF]
Maxwell's equations are a system of partial differential equations that govern the laws of electromagnetic induction. We study a mimetic finite-difference (MFD) discretization of the equations which preserves important underlying physical properties.

Local flux mimetic finite difference methods [PDF]
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 ...

Mimetic finite differences for elliptic problems [PDF]
In multi-physics codes used adaptive mesh refinement techniques and other special requirements for the solution of partial differential equations results in polyhedral meshes with possible degenerate elements. In comparison to other grids polyhedral meshes can improve the adaption of the grid to special requirements of the numerical solution and can ...

High order mimetic difference simulation of unsaturated flow using Richards equation
The vadose zone is the portion of the subsurface above the water table and its pore space usually contains air and water. Due to the presence of infiltration, erosion, plant growth, microbiota, contaminant transport, aquifer recharge, and discharge to ...

A mimetic finite difference method using Crank-Nicolson scheme for unsteady diffusion equation
n this article a new mimetic finite difference method to solve unsteady diffusion equation is presented. It uses Crank-Nicolson scheme to obtain time approximations and second order mimetic discretizations for gradient and divergence operators in space ...
