A finite difference scheme for the nonlinear time‐fractional partial integro‐differential equation

Mathematical methods in the applied sciences, 2020
In this paper, a finite difference scheme is proposed for solving the nonlinear time‐fractional integro‐differential equation. This model involves two nonlocal terms in time, ie, a Caputo time‐fractional derivative and an integral term with memory.

An improved fifth order alternative WENO-Z finite difference scheme for hyperbolic conservation laws

Journal of Computational Physics, 2018
An alternative formulation of conservative weighted essentially non-oscillatory (WENO) finite difference scheme with the classical WENO-JS weights (Jiang et al. (2013) [6] ) has been successfully used for solving hyperbolic conservation laws. However, it

Conservative finite difference scheme for the nonlinear fourth-order wave equation

Applied Mathematics and Computation, 2019
A conservative finite difference scheme is presented for solving the two-dimensional fourth-order nonlinear wave equation. The existence of the numerical solution of the finite difference scheme is proved by Brouwer fixed point theorem.

A New Finite-Difference Diffusion Scheme

Journal of Computational Physics, 1996
The authors purpose a new second-order accurate, explicit finite difference diffusion scheme, that they call ``three-level, locally implicit'' scheme. The scheme is derived as a weighted average of the conventional forward-in-time, explicit diffusion scheme over one grid length and the same scheme over two grid lengths.

Finite Difference Scheme

1984
To arrive at finite difference equations modeling magnetohydrodynamic equilibrium we use a technique that is motivated by the finite element method [3]. First we develop a second order accurate numerical quadrature formula for the Hamiltonian E based on a rectangular grid of mesh points over a unit cube of the space with coordinates s, u and v.

A reduced high-order compact finite difference scheme based on proper orthogonal decomposition technique for KdV equation

Applied Mathematics and Computation, 2018
In this paper, a reduced implicit sixth-order compact finite difference (CFD6) scheme which combines proper orthogonal decomposition (POD) technique and high-order compact finite difference scheme is presented for numerical solution of the Korteweg-de ...
