Abstract
Hierarchical discretization and model adaptivity is achieved by locally computed quantitative (absolute) global error estimators with strict upper bounds for the discretization error of the FE-solution with respect to the boundary value problem of the current mathematical model and also for a model within a nested sequence of models from lower to higher complexity for dimensions, kinematics and material behavior in order to account for boundary layers, stress concentrations, stiffness jumps etc. as well as for changes of material behavior (e.g. from elastic to elastoplastic deformations).
