Abstract In this paper we construct an upwind finite volume element scheme based on the Crouzeix-Raviart nonconforming element for nonselfadjoint elliptic problems. These problems often appear in dealing with flow in porous media. We establish the optimal order H1-norm error estimate. We also give the uniform convergence under minimal elliptic regularity assumption.
