      The paper deals with concrete problems of the computational method development for 3-D time-dependent gas dynamics problems on the irregular grids, which are represented by Dirihle cells and Voronoy bodies. The equations of time-dependent gas dynamics, the methods of initial grid construction and the difference scheme for solving equations are presented; a study of the possibility of retaining the cells convex during computation is performed.
