Local and parallel finite element algorithms based on two-grid discretization

Based on two-grid discretization we constract local and parallel finite element algorithms for three forms of the Navier-Stokes equations, which are penalty, primitive variable and stream function form. For every form the corresponding algorithm, the proof of convergence and error analysis and numerical results are given. The numerical simulations show these algorithms are reliable and efficient.
