Off-lattice Simulation of the Fractal Growth with Attractive Radial Drift and Mobility.
V.S. Gurin and V.P. Poroshkov

In the perfect off-lattice DLA model of the fractal growth the centre-attractive drift factor and mobility of particles are introduced. Simulation indicates variation of fractal patterns and their characteristics depending on these new factors. Noticeable effects of the drift factor upon fractal dimension, growth efficiency and frozen zone are shown. The mobility behaves in the competitive manner with the drift. The combination of drift and mobility is considered as analogs of potential and kinetic energies of particles.
Key words: fractal growth, the diffusion limited aggregation.
