  Due to errors of numerical methods, qualitative behavior of the numerically
simulated solution may be completely different from qualitative behavior of the
real trajectory. Therefor in study of attractors the more useful idea is to
simulate a bundle of trajectories for a (relatively) short time (see Dellnitz
etc.) We suggest a method of modelling Milnor's attractor of dissipative
dynamical system. It is based on numerical simulation of bundle of
trajectories, emanating from some set, and locating regions with high density
of trajectories. We present 2D and 3D examples of application of our method.
