Summary. A finite element method to approximate the vibration modes of a structure in contact with an incompressible fluid is analyzed
in this paper. The effect of the fluid is taken into account by means of an added mass formulation, which is one of the most
usual procedures in engineering practice. Gravity waves on the free surface of the liquid are also considered in the model.
Piecewise linear continuous elements are used to discretize the solid displacements, the variables to compute the added mass
terms and the vertical displacement of the free surface, yielding a non conforming method for the spectral coupled problem.
Error estimates are settled for approximate eigenfunctions and eigenfrequencies. Implementation issues are discussed and numerical
experiments are reported. In particular the method is compared with other numerical scheme, based on a pure displacement formulation,
which has been recently analyzed.
