A finite volume method based on the Crouzeix-Raviart element for elliptic PDE's in two dimensions
نویسنده
چکیده
We introduce and analyse a finite volume method for the discretization of elliptic boundary value problems in R2. The method is based on nonuniform triangulations with piecewise linear nonconforming spaces. We prove optimal order error estimates in the L2–norm and a mesh dependent H1–norm.

Generalized Aggregation-Based Multilevel Preconditioning of Crouzeix-Raviart FEM Elliptic Problems
Preconditioners based on various multilevel extensions of two-level finite element methods (FEM) are well-known to yield iterative methods of optimal order complexity with respect to the size of the system, as was first shown by Axelsson and Vassilevski [4]. The derivation of optimal convergence rate estimates in this context is mainly governed by the constant γ ∈ (0, 1) in the so-called Cauchy...
متن کاملA partially penalty immersed Crouzeix-Raviart finite element method for interface problems
The elliptic equations with discontinuous coefficients are often used to describe the problems of the multiple materials or fluids with different densities or conductivities or diffusivities. In this paper we develop a partially penalty immersed finite element (PIFE) method on triangular grids for anisotropic flow models, in which the diffusion coefficient is a piecewise definite-positive matri...
متن کاملGradient Recovery for the Crouzeix-Raviart Element
A gradient recovery method for the Crouzeix–Raviart element is proposed and analyzed. The proposed method is based on local discrete least square fittings. It is proven to preserve quadratic polynomials and be a bounded linear operator. Numerical examples indicate that it can produce a superconvergent gradient approximation for both elliptic equations and Stokes equations. In addition, it provi...
متن کاملAdaptive Finite Volume Scheme for Elliptic Problems
A new technique for the implementation of cell-centered nite volume schemes is proposed. It is based on a recently found equivalence between these schemes and the non-conforming Crouzeix-Raviart nite element approximation. Though the implementation somewhat increases the number of unknowns, it brings two signiicant advantages that make it attractive. On the one hand the resulting formulation is...
متن کاملDiscontinuous Finite Element Methods for Interface Problems: Robust A Priori and A Posteriori Error Estimates
Abstract. For elliptic interface problems in two and three dimensions, this paper studies a priori and residual-based a posteriori error estimations for the Crouzeix–Raviart nonconforming and the discontinuous Galerkin finite element approximations. It is shown that both the a priori and the a posteriori error estimates are robust with respect to the diffusion coefficient, i.e., constants in th...
