The work considers the influence of dust structures on the positive column of a glow discharge. A formula describing the radial distribution of ions in the case of an extended structure in the uniform positive column is proposed. To determine the flows of ions on a particle and the potential of its surface, approximation of simulation results by the method of molecular dynamics is proposed. Examples of calculations for specific conditions of experiments are presented.
