Convergence analysis of an upwind finite volume element method with crouzeix-raviart element for non-selfadjoint and indefinite problems
Based on Crouzeix-Raviart non-conforming elements for self-adjoint elliptic problems, the authors construct an upwind finite volume element scheme. An optimal order \(H^1\)-norm error estimate is established. Moreover, under minimal elliptic regularity assumption, the authors obtain a uniform convergence.
