Shear Piezos

Hello everyone,,
I am having a problem with Base Vector system settings for a shear piezo plate that I am modeling to shear in Z and then at some time X directions (see the attached model) . The tutorials that I have found online are helpful except for the coordinate system settings. In the link below, I am referring to page 7 of the pdf file, I don't understand how the coordinates x1 and x3 are changed.

How do I change the base vectors to achieve shearing in the X and Z directions. Any suggestions will be highly appreciated.
Thanks
Warm Regards

Possibly an easier way to do this is to define a rotated coordinate system (right-click Definitions) using the Euler angles. For your case they will be multiples of pi/2. Then under the settings for Piezoelectric Material you can select the rotated coordinate system.
A caution: it's easy to get confused with the Euler angles, it's a good idea to check against a hand calculation.
