Both the finite difference method (FDM) and the finite element method (FEM) treating the Navier-Stokes equation (NS) and the equation of continuity (EC) are generally used for the numerical analysis of viscous flows. In this paper we propose a new FEM without the NS and the EC for steady viscous flows. The formulation of the FEM is based on a hybrid type of the virtual work principle used in solid mechanics. To investigate the validity of the present FEM, we calculate a two-dimensional cavity flow. The results calculated by the FEM agree well with those by the FDM. A merit of the FEM makes it easy to treat boundary conditions that the quantities on the boundary are hydrodynamic ones such as velocity and/or pressure.
