AB - <p style="text-align: justify;">In this paper the numerical method for solution of an aeroelastic model describing the interactions of air flow with vocal folds is described. The flow is modelled
by the incompressible Navier-Stokes equations spatially discretized with the aid of the
stabilized finite element method. The motion of the computational domain is treated
with the aid of the Arbitrary Lagrangian Eulerian method. The structure dynamics is
replaced by a mechanically equivalent system with the two degrees of freedom governed by a system of ordinary differential equations and discretized in time with the
aid of 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 from literature.</p>
