Abstract. In this paper, we describe the application of the discrete element method to solve a specific electrodynamic problem, namely, to study the refractive properties of the flow that drags the finely dispersed impurities placed in it. The study of the problem consists of a number of full-scale tests and setting up a target computational experiment on the model using the discrete element method to obtain data for verification of a subsequent laboratory study. The main emphasis in this work is done on the indicated experiment, whereas modeling by the discrete element method is proposed to be used as a possible tool of the functional cycle of approbation of theoretical provisions. The study is carried out on the example of an iron powder with known parameters placed in a moving liquid. Refractive properties are studied by the waveguide method. A model of dynamic modeling, a connection of the method of discrete elements with the finite element method, and the setting up of physical simulation conditions are proposed.

Key words: discrete element method, dynamic modeling, particles, flow, electromagnetic refraction.
