The recent results of applying the parallel numerical code SELFAS-3 to modelling of electrodynamic aggregation of magnetized nanodust are presented. The modelling describes evolution of a many-body system of basic blocks which are taken as strongly magnetized thin rods (i.e., one-dimensional static magnetic dipoles), with electric conductivity and static electric charge, screened with its own plasma sheath. The code provides continuous modelling of the following stages of evolution: (i) alignments of randomly situated solitary basic blocks in an external magnetic field and formation of stable filaments, (ii) percolation of electric conductivity in a random filamentary system, and electric short-circuiting in the presence of an external electric field, (iii) evolution of electric current profile in a filamentary network with a trend towards a fractal skeletal structuring.
