The comets play important role as a simulation laboratory
for multiscale kinetic
plasma processes which are
key-role processes in space and laboratory
plasmas. A development of multiscale combined numerical methods allows us
to use more realistic cometary plasma models (see, e.g. [H\"aberli et al., 1997;
Delamere et al.,
1999; Bagdonat and Motschmann, 2002; Lipatov et al., 2002]).
In this report, we develop a Particle-Ion--Fluid-Ion--Fluid--Electron method
of kinetic ion-neutral simulation (see, e.g. [Lipatov, 2002]),
which is based on a
multiscale adaptive mesh, particle and algorithm refinement.
This method takes
into account
charge-exchange and photoionization processes. The first results of such
simulation of the dynamics of ions near comet Borrelly
are discussed in this report.
