Domain decomposition finite element/finite difference method for the conductivity reconstruction in a hyperbolic equation

open access: yes, 2015
We present domain decomposition finite element/finite difference method for the solution of hyperbolic equation. The domain decomposition is performed such that finite elements and finite differences are used in different subdomains of the computational ...

A Two-Level Method for Mimetic Finite Difference Discretizations of Elliptic Problems [PDF]

open access: yes, 2014
We propose and analyze a two-level method for mimetic finite difference approximations of second order elliptic boundary value problems. We prove that the two-level algorithm is uniformly convergent, i.e., the number of iterations needed to achieve ...

Difference potentials method based on LOD splitting technique for nonlinear convection–diffusion equations with interfaces [PDF]

open access: yesAUT Journal of Mathematics and Computing
In this paper, we construct a difference potentials method (DPM) based on the locally one-dimensional (LOD) technique to solve the two-dimensional nonlinear convection-diffusion interface problems. The advantage of using the LOD scheme is that the linear

Modelling metallic discontinuities with the non-orthogonal finite difference time domain method [PDF]

open access: yes, 2004
Numerical electromagnetic models, such as the finite difference time domain (FDTD) method, have many applications. The authors focus on the non-orthogonal FDTD method, which offers an improved geometric flexibility compared to other standard techniques ...

Conservative and non-conservative methods based on hermite weighted essentially-non-oscillatory reconstruction for Vlasov equations [PDF]

open access: yes, 2013
We introduce a WENO reconstruction based on Hermite interpolation both for semi-Lagrangian and finite difference methods. This WENO reconstruction technique allows to control spurious oscillations.

Re-constructing the river bed using the streamline-generation method

open access: yesMethodsX
River bed reconstruction plays an essential part in supporting the hydrodynamic simulation and understanding the morphological processes of a river. The streamlines can be solved using Laplace equations.
