Abstract

In this paper an automatic procedure for finite element analysis of two-dimensional linear elastic structures is presented. This feedback procedure involves geometric modelling, automatic mesh generation, estimation of discretization errors, detection of regions of high stress gradients, estimation of error convergence rates, mesh optimization, and mesh refinement. A strategy is implemented for selecting intermediate meshes in cases of height accuracy requirements. The final meshes are optimal in the sense that the requirements are fulfilled with minimum computational efforts. Some additional mesh optimality criteria are also considered so as to meet specific local criteria. Three numerical examples are presented to show the different aspects and the efficiency of the procedure.
