  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.
