Superconvergence for Control-Volume Mixed Finite Element Methods on Rectangular Grids
We consider control-volume mixed finite element methods for the approximation of second-order elliptic problems on rectangular grids. These methods associate control volumes (covolumes) with the vector variable as well as the scalar, obtaining local algebraic representation of the vector equation (e.g., Darcy’s law) as well as the scalar equation (e.g., conservation of mass). We establish O(h2)...

A new mixed nite element method on totally distorted rectangular meshes is introduced with optimal error estimates for both pressure and velocity This new mixed discretization ts the geometric shapes of the discontinuity of the rough coe cients and domain boundaries well This new mixed method also enables us to derive the optimal error estimates and existence and uniqueness of Thomas s mixed ni...
متن کاملSuperconvergence and Extrapolation for Mixed Finite Element Methods on Rectangular Domains
Asymptotic expansions for the RT (Raviart-Thomas) mixed finite element approximation by the lowest-order rectangular element associated with a second-order elliptic equation on a rectangular domain are derived. Superconvergence for the vector field along the Gauss lines is obtained as a result of the expansion. A procedure of postprocessed extrapolation is presented for the scalar field, as wel...
متن کاملUniform Convergence and Superconvergence of Mixed Finite Element Methods on Anisotropically Refined Grids
The lowest order Raviart-Thomas rectangular element is considered for solving the singular perturbation problem ?div(arp) + bp = f; where the diagonal tensor a = (" 2 ; 1) or a = (" 2 ; " 2): Global uniform convergence rates of O(N ?1) for both p and a 1=2 rp in the L 2-norm are obtained in both cases, where N is the number of intervals in both directions. The pointwise interior (away from the ...
متن کاملInterior superconvergence in mortar and non-mortar mixed finite element methods on non-matching grids
We establish interior velocity superconvergence estimates for mixed finite element approximations of second order elliptic problems on non-matching rectangular and quadrilateral grids. Both mortar and non-mortar methods for imposing the interface conditions are considered. In both cases it is shown that a discrete L2-error in the velocity in a compactly contained subdomain away from the interfa...
