Benchmark solutions are presented for a simple linear elastic boundary value problem, as analysed using a range of finite element mesh configurations. For each configuration, various estimates of local (i.e. element) and global discretization error have been computed. These show that the optimal mes

✦ Synopsis
we analyze the absolute error estimate of Auchmuty [l] developed for linear systems.
In the Euclidean norm, this estimate and its geometrical interpretation are derived from the Kantorovich inequality. The estimate is then compared with other estimates known in the literature. A probabilistic analysis and extension of the estimate to nonlinear systems are also given. We also report on computational test results, which indicate that Auchmuty's estimate is an appropriate tool for practice.

## Abstract In this paper we discuss an __a posteriori__ interpolation error estimate based on the Hessian of the surface and we propose a new geometric error estimate related to the local deformation of the surface. The new approach makes possible the construction of adapted geometric meshes for s
