    Notes: We present a numerical procedure to eliminate internal nodes from elements designed to approximate incompressible flow problems. We compare six elements in academic and industrial like flow problem and we discuss their relative qualities. A surprising conclusion is that richer elements may behave less well than simple ones if a good enforcement of incompressibility is not maintained.

    A generalization of Uzawa's algorithm for the solution of the Navier-Stokes equations (1985)

    Notes: Usawa's algorithm provides an efficient method for solving the divergence-free Stokes problem. On the other hand, the Newton-Raphson scheme is very popular for the solution of the nonlinear Navier-Stokes equations. We propose here a new method that combines these two algorithms and converges to a divergence-free solution of the nonlinear Navier-Stokes equations.
