Resumen:
An arbitrary Lagrangian-Eulerian method is used for solving incompressible free-surface flows with the finite element method, assuming that the fluid is viscous and Newtonian. The flow is represented over a domain with a single fluid, where one of the frontiers is a free surface. The main attention here is focused on open domains, where artificial boundaries are introduced in order to bound the numerical problem. An absorbing boundary condition is developped based on the shallow water approximation in the form of an absorbing layer. The absorbing properties of this artificial medium are assessed and numerical examples are presented.
