The Navier-Stokes equations are spatially discretized with the aid of the stabilized FE method. The motion of the computational domain is treated with the aid of ALE method. The structure dynamics is replaced by a kinematically equivalent system with the two degrees of freedom governed by a system of ordinary differential equations and discretized in time by an implicit multistep method and strongly coupled with the flow model. The influence of inlet/outlet boundary conditions is studied and the numerical analysis is performed and compared to the related results obtained for the phonation onset by using a simplified flow model.
