This paper deals with the analytic and FEM analysis of sloshing frequency response for incompressible, invicid and irrotational flow in two dimensional rectangular tank. We use Laplace equation based on potential theory as governing equation. For small amplitude sloshing motion, the linearized free surface condition was applied and the solution was calculated by the separation of variables. To avoid the divergence of response at resonance frequencies, artificial damping is introduced. Also, this problem was solved by FEM using 9-node elements in orther to compare with the analytical solution.
