6.3 Postprocessing

In this phase several operations which are not coupled to the nonlinear equation system are performed. One of these tasks is the calculation of the overall contact charge Q out of the charge density $\rho$. The other task of this phase is the management of the history information. As already outlined in Section 3.2, the electric field and polarization of the last turning point are decisive for the calculation of the subcycles of the hysteresis. Therefore, history of the devices is evaluated and the turning points which are needed for the next operating points, namely $E_\mathrm{next}$ and $P_\mathrm{next}$ are provided. A schematic overview of these tasks is given Fig. 6.9.
