Parallel simulation of three-dimensional free-surface fluid flow problems T. A. Baer\ S. R. Subia^ and P. A. Sackinger^ ^Incompressible Fluid Mechanics Department ^•Computational Thermal/Fluid Engineering Sciences, Sandia National Laboratories, USA Abstract We describe parallel simulations of viscous, incompressible, free surface, Newtonian fluid flow problems that include dynamic contact lines. The Galerkin finite element method was used to discretize the fully-coupled gov- erning conservation equations and a "pseudo-solid" mesh mapping approach was used to determine the shape of the free surface. In this approach, the fi- nite element mesh is allowed to deform to satisfy quasi-static solid mechanics equations subject to geometric or kinematic constraints on the boundaries. As a result, nodal displacements must be included in the set of problem unknowns. Issues concerning the proper constraints along the solid-fluid dynamic contact line in three dimensions are discussed. Pa
