In BabuSka et al. (Cornput. Meth. appl. Mech. Engng, 114,307-37X (1994); IN. J. numer. Meth. Engng 37, 1073-l 123 (1994) ) we presented a model study of (1 posteriori error estimators in the interior of finite element meshes using a computer-based methodology. In this paper we investigate further the quality of element-residual error estimators. We analyzed several versions of the element-residual estimator and based on this study we propose recipes for robust estimators.
