Multipoint data obtained in recent multi-spacecraft studies lead to
advance in such complex problems of shock of physics as the magnetic
ramp structure and shock nonstationarity. PIC simulations are an
important tool in studies of shocks in a broad range of parameters
typical for heliospheric shocks and astrophysical shocks as well.
Appropriate choice of the simulation parameters, like the
electron-to-proton mass ratio and the ratio of the plasma frequency to
the gyrofrequency, is crucial to proper interpretation of the results
and comparison with observations. We discuss the parameter scaling in
the existing PIC simulations and their applicability to the observations
of the heliospheric shocks.
