چکیده

In this study, we obtain a numerical solution for Fisher's equation using experiment with three different cases. The cases correspond to coefficients the reaction term. We use methods namely; Forward-Time Central Space (FTCS) scheme, Nonstandard Finite Difference (NSFD) and Explicit Exponential (EEFD) scheme. first study properties of schemes such as positivity, boundedness, stability convergence estimates. then values L 1 ∞ errors in order an estimate optimal time step size at given value spatial size. determine if is influenced by choice or coefficient term used. Finally, compute rate all

Convergence of Finite Difference Methods for Poisson’s Equation with Interfaces

In this paper, a weak formulation of the discontinuous variable coefficient Poisson equation with interfacial jumps is studied. The existence, uniqueness and regularity of solutions of this problem are obtained. It is shown that the application of the Ghost Fluid Method by Fedkiw, Kang, and Liu to this problem in [9] can be obtained in a natural way through discretization of the weak formulatio...

Nonlinear stability and convergence of finite-difference methods for the good Boussinesq equation

Note that 40 determines the initial position of the wave, and that, due to the square root in (1.2), the parameter P can only take values in 0<P=< 1. Thus, the solitary waves (1.1) only exist for a finite range of velocities l < c < l . Of course, a positive (respectively negative) velocity corresponds to a wave moving to the right (respectively to the left). When two solitary waves with parame...

Finite Element Methods for Convection Diffusion Equation

This paper deals with the finite element solution of the convection diffusion equation in one and two dimensions. Two main techniques are adopted and compared. The first one includes Petrov-Galerkin based on Lagrangian tensor product elements in conjunction with streamlined upwinding. The second approach represents Bubnov/Petrov-Galerkin schemes based on a new group of exponential elements. It ...

Optimal Rate of Convergence for a Nonstandard Finite Difference Galerkin Method Applied to Wave Equation Problems

The optimal rate of convergence of the wave equation in both the energy and the L-norms using continuous Galerkin method is well known. We exploit this technique and design a fully discrete scheme consisting of coupling the nonstandard finite difference method in the time and the continuous Galerkin method in the space variables. We show that, for sufficiently smooth solution, the maximal error...

The Optimal Convergence Rate of Monotone Finite Difference Methods for Hyperbolic

We are interested in the rate of convergence in L1 of the approximate solution of a conservation law generated by a monotone finite difference scheme. Kuznetsov has proved that this rate is 1/2 [USSR Comput. Math. Math. Phys., 16 (1976), pp. 105–119 and Topics Numer. Anal. III, in Proc. Roy. Irish Acad. Conf., Dublin, 1976, pp. 183–197], and recently Teng and Zhang have proved this estimate to ...
