Abstract
Finite volume element method for the Stokes problem is considered. We use a conforming piecewise linear function on a fine grid for velocity and piecewise constant element on a coarse grid for pressure. For general triangulation we prove the equivalence of the finite volume element method and a saddle-point problem, the inf-sup condition and the uniqueness of the approximation solution. We also give the optimal order H1 norm error estimate. For two widely used dual meshes we give the L2 norm error estimates, which is optimal in one case and quasi-optimal in another case. Finally we give a numerical example.
