Abstract
In this paper, we introduce a finite volume element method for the Navier–Stokes problem. This method is based on the multiscale enrichment and uses the lowest finite element pair P 1/P 0. The stability and convergence of the optimal order in H 1-norm for velocity and L 2-norm for pressure are obtained. Using a dual problem for the Navier–Stokes problem, we establish the convergence of the optimal order in L 2-norm for the velocity.
