Random walks in a disordered medium with a dipole-dipole transport are studied. It is proved that the long-time asymptotic behavior is of a diffusion character and the diffusion coefficient is determined* The analysis is based on a new, efficient, numerical-modeling method employing direct calculation of the Fourier transform of the propagator and periodic continuation of the system without periodic continuation of the initial condition. © 1995 Arrierican Institute of Physics.
