The piezoelectric ceramics are poled along their thickness direction such that the transduction occurs in the d33 mode.
Because the poling of piezoelectric elements such as the rings used in Tonpilz transducers can be assumed to be uniform, we will use a so-called Cartesian polarization for each one of the transducing elements.
To define Cartesian polarizations, Local Axes are used. The direction of the polarization is given by the z axis of the local axes.
First, select the Surface tab of the conditions window; then Polarization from the drop-down list.
