Comput. Phys. Commun. 181, No. 3, 557-561 (2010).

The solution of the advection-dispersion equation of fractional order
\[ \frac{\partial^{\alpha}u(x,t)}{\partial t^{\alpha}}+ v(x,t)D_{x}^{\nu}u(x,t)-k(x,t)D_{x}^{\beta}u(x,t)=F(x,t) \]
with homogeneous initial and boundary conditions is presented in the form of Fourier series. The approximate solution is obtained by truncating this series.
