  author={Feby Abraham and Marek Behr},
Difficulties associated with free-surface finite element flow simulations are related to a) nonlinear and advective nature of most hydrodynamic flows, b) requirements for compatibility between velocity and pressure interpolation, c) maintaining a valid computational mesh in the presence of moving boundaries, and d) enforcement of the kinematic conditions at the free surface. Focusing on the last issue, we present an extension of the free surface elevation equation to cases where the prescribed… CONTINUE READING
