A Posteriori Error Analysis of Space-Time Finite Element Discretizations of the Time-Dependent Stokes Equations
We present a novel a posteriori error analysis of spacetime finite element discretizations of the time-dependent Stokes equations. Our analysis is based on the equivalence of error and residual and a suitable decomposition of the residual into spatial and temporal contributions. In contrast to existing results we directly bound the error of the full space-time discretization and do not resort t...
متن کاملA posteriori error analysis of the fully discretized time-dependent Stokes equations
The time-dependent Stokes equations in twoor three-dimensional bounded domains are discretized by the backward Euler scheme in time and finite elements in space. The error of this discretization is bounded globally from above and locally from below by the sum of two types of computable error indicators, the first one being linked to the time discretization and the second one to the space discre...
متن کاملA Posteriori Error Analysis of the Time Dependent Stokes Equations with Mixed Boundary Conditions
In this paper we study the time dependent Stokes problem with mixed boundary conditions. The problem is discretized by the backward Euler’s scheme in time and finite elements in space. We establish an optimal a posteriori error with two types of computable error indicators, the first one being linked to the time discretization and the second one to the space discretization.

In this paper we study the time dependent Navier-Stokes problem with mixed boundary conditions. The problem is discretized by the backward Euler’s scheme in time and finite elements in space. We establish optimal a posteriori error estimates with two types of computable error indicators, the first one being linked to the time discretization and the second one to the space discretization. We fin...
متن کاملA posteriori error analysis for time-dependent Ginzburg-Landau type equations
This work presents an a posteriori error analysis for the finite element approximation of time-dependent Ginzburg-Landau type equations in two and three space dimensions. The solution of an elliptic, self-adjoint eigenvalue problem as a postprocessing procedure in each time step of a finite element simulation leads to a fully computable upper bound for the error. Theoretical results for the sta...
