Previously on the blog, we detailed the standards employed to describe piezoelectric materials. There are two piezoelectric material standards supported in COMSOL Multiphysics: the IRE 1949 standard and the IEEE 1978 standard. Today, we will demonstrate how to set up the orientation of a crystal, specifically an AT cut quartz plate, within both standards.
