This contribution is focused on the analysis of dynamic behavior of elastic body moving in liquid. In many technical applications this motion is with large displacements. Some technical applications can be vibration of blades or rotors in centrifugal pumps or water turbines. But on other hand presented approach has more general application. Because of are assumed the large displacements, this analysis is nonlinear and modal behavior depends on a parameters. There is very difficult or impossible to do this analysis using commercial programme systems. It is caused by limited number of boundary conditions for contact between body and liquid in these systems. In this contribution is presented the mathematical model of a new type of boundary conditions which allowed the modal analysis and computing the steady state response. In principle this analysis is if the frequency domain. It is necessary provided some testing, because this approach is new. For this case, the curvilinear co-ordinates were chosen. The Bézier body was chosen for the description of geometrical configuration and also for approximation the solution. MATLAB programme code was chosen for software processing
