A numerical model for investigation of the 3D motion of matter in a gravitational field is proposed. The model satisfies all fundamental conservation laws. For acceleration of computations an effective parallel algorithm for use on multiprocessor computers with distributed memory is implemented. The results of the numerical experiments with the initial distribution of matter in the form of a plane disk are presented. These experiments are aimed to define the parameters' values, which lead to the stability of the disk with respect to asymmetrical disturbances directed along the axis of rotation and to the spiral gravity waves.
