Effect of Anisotropic Localization in a Ferroelectric Multiscale Model

In this article, the effect of various localization rules in a ferroelectric multiscale model is studied. Ferroelectric materials are highly heterogeneous materials, which means local fields vary from grain to grain. Many localization rules can be used in multiscale models to consider for this heterogeneity. In this article, three localization rules are implemented, providing results, which are compared and analyzed. The results show that anisotropic localization should be preferred for more accurate predictions.
