Abstract
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.
