This paper deals with an interaction between the fluid flow and an elastic body. A simplified model of the human vocal fold is considered. In order to capture deformation of the elastic body the arbitrary Lagrangian-Euler method (ALE) is used. The viscous incompressible fluid flow and linear elasticity models are considered. The problem is solved by the developed finite element method (FEM) based solver. Particularly, for the flow approximation the crossgrid elements are used, whereas for the elastic structure the piecewise linear elements are employed. Results of numerical experiments are shown.
