چکیده

In this paper, the Lax-Wendroff difference scheme has been presented for solving one-dimensional wave equation with integral boundary conditions. First, given solution domain is discretized and derivative involving spatial variable replaced by central finite approximation of functional values at each grid point using Taylor series expansion. Then, resulting second-order linear ordinary differential equation, displacement function in direction a temporal expansion developed, then it gives system algebraic equations. The initial condition also method. Then obtained equations solved matrix inverse stability convergent analysis are investigated. established convergence further accelerated applying Richardson extrapolation which yields fourth-order sixth-order variable. To validate applicability proposed method, three model examples considered different mesh sizes both directions. Numerical results tables terms maximum absolute error,    and  norm.  numerical

Differential Transform Method to two-dimensional non-linear wave equation

In this paper, an analytic solution is presented using differential transform method (DTM) for a class of wave equation. The emphasis is on the nonlinear two-dimensional wave equation. The procedures introduced in this paper are in recursive forms which can be used to obtain the closed form of the solutions, if they are required. The method is tested on various examples, and the results reveal ...

A posteriori error estimation for the Lax-Wendroff finite difference scheme

In many application domains, the preferred approaches to the numerical solution of hyperbolic partial differential equations such as conservation laws are formulated as finite difference schemes. While finite difference schemes are amenable to physical interpretation, one disadvantage of finite difference formulations is that it is relatively difficult to derive the so-called goal oriented a po...

A Multilevel Finite Difference Scheme for One-Dimensional Burgers Equation Derived from the Lattice Boltzmann Method

An explicit finite difference scheme for one-dimensional Burgers equation is derived from the lattice Boltzmannmethod. The system of the lattice Boltzmann equations for the distribution of the fictitious particles is rewritten as a three-level finite difference equation. The scheme is monotonic and satisfies maximum value principle; therefore, the stability is proved. Numerical solutions have b...
