Strong Superconvergence of Finite Element Methods for Linear Parabolic Problems
We study the strong superconvergence of a semidiscrete finite element scheme for linear parabolic problems on Q Ω × 0, T , where Ω is a bounded domain in R d ≤ 4 with piecewise smooth boundary. We establish the global two order superconvergence results for the error between the approximate solution and the Ritz projection of the exact solution of ourmodel problem inW1,p Ω and Lp Q with 2 ≤ p < ...
متن کاملSuperconvergence of the mixed nite element approximations to parabolic equations
Semidiscrete mixed nite element approximation to parabolic initial boundary value problems is introduced and analyzed Superconver gence estimates for both pressure and velocity are obtained The esti mates for the errors in pressure and velocity depend on the smoothness of the initial data including the limiting cases of data in L and data in H r for r su ciently large Because of the smoothing p...
متن کاملFinite Element Methods for Parabolic Equations
The initial-boundary value problem for a linear parabolic equation with the Dirichlet boundary condition is solved approximately by applying the finite element discretization in the space dimension and three types of finite-difference discretizations in time: the backward, the Crank-Nicolson and the Calahan discretization. New error bounds are derived.
متن کاملSuperconvergence of mixed finite element methods for optimal control problems
In this paper, we investigate the superconvergence property of the numerical solution of a quadratic convex optimal control problem by using rectangular mixed finite element methods. The state and co-state variables are approximated by the lowest order Raviart-Thomas mixed finite element spaces and the control variable is approximated by piecewise constant functions. Some realistic regularity a...
متن کاملA new positive definite semi-discrete mixed finite element solution for parabolic equations
In this paper, a positive definite semi-discrete mixed finite element method was presented for two-dimensional parabolic equations. In the new positive definite systems, the gradient equation and flux equations were separated from their scalar unknown equations. Also, the existence and uniqueness of the semi-discrete mixed finite element solutions were proven. Error estimates were also obtaine...
