Finite-difference methods [PDF]

open access: possible, 2001
In previous chapters, we have discussed the equations governing the structure of a steady flow and the evolution of an unsteady flow, and derived selected solutions for elementary flow configurations by analytical and simple numerical methods. To generate solutions for arbitrary flow conditions and boundary geometries, it is necessary to develop ...

Comparison of Caputo and conformable derivatives for time-fractional Korteweg–de Vries equation via the finite difference method

International Journal of Modern Physics B, 2018
In this study, we investigate the nonlinear time-fractional Korteweg–de Vries (KdV) equation by using the (1/G[Formula: see text])-expansion method and the finite forward difference method.

Finite Difference Methods

2011
Finite difference methods were used for solving differential equations long before computers were available. As we have seen in Chap. 2, these methods arise quite naturally by going back to the definition of derivatives, and just stopping short of taking the limit as the step size tends to zero.

Finite Difference Method

2001
The finite difference method is a universally applicable numerical method for the solution of differential equations. In this chapter, for a sample parabolic partial differential equation, we introduce some difference schemes and analyze their convergence. We present the well-known Lax equivalence theorem and related theoretical results, and apply them

Finite Difference Methods [PDF]

open access: possible, 1983
If very complex conditions have to be considered for special cases, such as a time-dependent change in the sustained load, the interaction of concretes of different ages at loading, or a systems change during the creep and shrinkage process, the step-by-step method frequently offers the only, if rather laborious, way to solve the problem.

Finite-Difference Methods

1995
Finite-difference methods are important for two reasons. First, they form the background to almost all later developments. Secondly, a finite-difference method is relatively easy to construct and program to solve a particular problem, or class of problems, that may not be suitable for an existing general purpose software package using, say, finite ...

Finite Difference Methods

2013
Here we give a brief introduction to finite difference methods. We first explain the implicit method; then we move to the explicit method. The former is more robust, in that it converges to the solution of a partial differential equation as the discrete increments of the state variables approach zero.

Finite Difference Methods

2019
The SWE are a system of two nonlinear hyperbolic PDEs that must be numerically solved to describe the time evolution of the fluid velocity and water depth in the entire computational domain. Finite-difference methods to obtain approximate numerical solutions are described in this chapter. First, basic numerical aspects are presented. The implementation

The Finite Difference Method [PDF]

open access: possible, 1999
The finite difference method was traditionally used in electron optics for solving field distributions. Even for magnetic field calculations, where the finite element method has largely replaced it, there are instances where the finite difference method is still advocated [1]. Finite elements are closely related to finite differences, indeed, there are

Finite difference method for time-space-fractional Schrödinger equation

International Journal of Computational Mathematics, 2015
In this paper, an implicit finite difference scheme for the nonlinear time-space-fractional Schrödinger equation is presented. It is shown that the implicit scheme is unconditionally stable with experimental convergence order of O(τ2−α+h2), where τ and h
