Abstract: Results of computational analysis of some nonlinear 3D-flow systems are discribed. The systems are global dissipative and demonstrate complex behaviour. Generated strange attractors may have stable quasihyperbolic attractor (type of a Lorenz «butterfly») and quasiattractors. Time bifurcations, multistable regimes and chaotization by the doubling-period cascades and by the iritermittency are found. The investigation of dynamical characteristics of the systems has been carried out numerically by the program package «Nonlinear dynamical systems» (like a problem solver environment).
