Journal of Applied Mathematics, 2013, vol. 2013, issue 1

Abstract: The stationary fractional advection dispersion equation is discretized by linear finite element scheme, and a full V‐cycle multigrid method (FV‐MGM) is proposed to solve the resulting system. Some useful properties of the approximation and smoothing operators are proved. Using these properties we derive the convergence results in both L2 norm and energy norm for FV‐MGM. Numerical examples are given to demonstrate the convergence rate and efficiency of the method.
