Robust residual a posteriori error estimators for the Reissner-Mindlin eigenvalues system

Undertaking numerical testing of new element designs that might have been tedious, lengthy and error prone with a traditional FE package where ‘elements’ (function spaces) and

It turns out that this enriched space can be embedded into the standard Hybrid High-Order (HHO) space for elasticity originally introduced in [21] (see also [20, Chapter 7] and [12]

In this paper, we are interested in deriving a reliable and efficient a posteriori residual error estimator for the finite element resolution of the A − ϕ formulation of the

We propose a new robust a posteriori error estimator based on H (div ) con- forming finite elements and equilibrated fluxes.. It is shown that this estimator gives rise to an

In this work we propose and analyze two estimators (η and ˜ η) of residual type associated with two mixed finite element approximations of the two-dimensional frictionless

In Tables 5.5 through 5.10 we provide the individual and total errors, the experimental rates of convergence, the a posteriori error estimators, and the effectivity indices for

To deal with these situations, we propose robust a posteriori error estimates for the heat equation with discontinuous, piecewise constant coefficients based on a discretization

This paper deals with the a posteriori analysis of the heat equation approximated using backward Euler’s scheme in time and a (piecewise linear) nonconforming finite
