SENSITIVITY ANALYSIS FOR BOUNDARY ELEMENT ERROR ESTIMATION AND MESH REFINEMENT
✍ M. GUIGGIANI 📂 Article 📅 1996 🏛 John Wiley and Sons 🌐 English ⚖ 977 KB

The subject of this paper is the sensitivity analysis of approximate boundary element solutions with respect to the positions of the collocation points. The direct differentiation approach is considered here and the analysis is performed analytically. Since only the collocation points are perturbed,

Modified h-method with directional error estimate for finite element stress analysis

An effective directional error estimator, based on Zienkiewicz-Zhu's error estimate, is presented for the h-method of the adaptive finite element analysis. The estimator allows Zienkiewicz-Zhu's error to be effectively separated into directional components in the global coordinate system and can be
