An unstructured grid-based, parallel solver has been developed for solving viscous free surface hydrodynamics problems. The overall scheme combines a finite-element, equal-order, projection-type three-dimensional incompressible flow solver with a finite element, two-dimensional advection equation solver for the free surface equation. The solution is marched in time until a steady state is reached. The unstructured grid enhances geometrical flexibility when treating complex geometries, and the parallel implementation permits fast turnaround of numerical simulations. A number of flows of practical interest are analyzed to demonstrate the numerical performance of the present approach.
