6.1.1.1 Control Parameters

It is necessary to apply control parameters in order to define basic features of the simulator, e.g. which models have to be used, the iteration limits and so on. An overview of the part of the control concept dealing with the simulation of ferroelectrics is given in Fig. 6.2.

The keywords used for the simulation of ferroelectric materials are listed in Table 6.1.

Table 6.1: Control parameters

Keyword	Values	Default
Ferro1d	yes,no	no
Anisotropy	yes,no	no
FerroTrans	yes,no	no

The keyword Ferro1d functions as a switch which decides whether the simplified one-dimensional algorithm, outlined in Subsection 4.2.7 is applied or not. This keyword is set to no by default.

The keyword Anisotropy distinguishes whether the model for anisotropy (value set to yes) or the model for homogeneous properties (value set to no) is used. This keyword is set to no by default.

The keyword FerroTrans distinguishes whether the transient model is used or not. This keyword is set to no by default.
