Authors investigate the problem of body or system of bodies motion in uid. Bodies may move according to predened rule of move under the in uence of uid forces and external forces (for example, gravity force). The modeling of the ow past bodies is done with vortex method within the model of ideal incompressible uid. With this the flow separation is suggested on predened separation lines. Evolution of vortex wake is done within Lagrange approach. To nd motion law together with uid equations the dynamic equations are solved.
