The goal of the investigation is to analyze of the numerical simulations of the dusty torus in active galactic nuclei and to construct the velocity and velocity dispersion maps. The methods of the investigation are numerical simulations of the N-body dynamic problem, the ray tracing algorithms. The results and their novelty are the following. 1. We obtained the maps of temperature distribution in the torus taking into account the heating of clouds by anisotropic radiation of the accretion disk. 2. It is shown that the torus is stable even for the case when the mass of the torus is equal to the mass of a supermassive black hole and the shape of the torus cross-section depends on its mass ratio. 3. We simulated the model maps of velocity distribution taking into account the effects of obscuration and wind influence for different angles of torus orientation relative to an observer. 4. We suggested an interpretation of the X-shape of the observational radio emission in the central region of NGC 1068. 5. The interpretation of the visible counter-rotation in the torus of NGC 1068, which is related to the asymmetric wind influence and orientation effects. 6. New approximate expressions for the outer gravitational potential of a torus with an elliptical cross-section were obtained using different methods.
