چکیده
In this paper, we investigate a practical numerical method for solving one-dimensional two-sided space-fractional diffusion equation with variable coefficients in finite domain, which is based on the classical Crank-Nicolson (CN) combined Richardson extrapolation. Second-order exact estimates time and space are obtained. The unconditional stability convergence of tested. Two examples also presented compared solution.

A second-order accurate numerical approximation for the fractional diffusion equation
Fractional order diffusion equations are generalizations of classical diffusion equations, treating super-diffusive flow processes. In this paper, we examine a practical numerical method which is second-order accurate in time and in space to solve a class of initial-boundary value fractional diffusive equations with variable coefficients on a finite domain. An approach based on the classical Cr...

We study a generalized Crank–Nicolson scheme for the time discretization of a fractional wave equation, in combination with a space discretization by linear finite elements. The schemeuses a non-uniformgrid in time to compensate for the singular behaviour of the exact solution at t = 0. With appropriate assumptions on the data and assuming that the spatial domain is convex or smooth, we show th...
