Represents Adaptive Non-LinearStatic problem. Solution is performed as a series of increments (loading or displacement). The error is estimated at the end of each load increment (after equilibrium is reached), and based on reached error, the computation continues, or the new mesh densities are generated and solution stops. Then the new discretization should be generated. The truly adaptive approach is supported, so the computation can be restarted from the last step (see section 1.1), solution is mapped to new mesh (separate solution step) and new load increment is applied. Of course, one can start the analysis from the very beginning using new mesh. Currently, the available estimators/indicators include only linear Zienkiewicz-Zhu estimator and scalar error indicator. Please note, that adaptive framework requires specific functionality provided by elements and material models. For details, see element and material model manuals.
