Piezoelectric coupling matrix input formatting

Please login with a confirmed email address before reporting spam

I'm inputing the Voigt notation piezoelectric coupling matrix for strain-charge form into the "Material Contents" table. Can someone confirm that the formatting below is the proper notation?

My input: {{0,0,0,0,d15,0}, {0,0,0,d15,0,0}, {d31,d31,d33,0,0,0}}

where d15 and so on are replaced by the corresponding values in SI units.
