What kind of strain or stress should I be reading in the results for piezoelectric simulation

Hi,

I am doing a piezoelectric simulation and using a force, I have displaced the piezoelectric cantilever. However, in the results section, I'm not sure which type of strain should I be looking at as there are so many options available. I just want to know the typical strain in the x direction (1-dir) and z-dir (3-dir). Thanks.

Regards,
Lionel
