In .ep they are labelled strain_xx, ..., strain_xy, strain_xz, strain_yz. I assume these are mislabeled. Or are they actually in incorrect order? StressSolve manual puts yz before xz just like t_V.
And out of curiosity, what am I looking at (with the order fixed?)...
(e_xx, e_yy, e_zz, e_xy, e_yz, e_xz) or
e_V = (e_xx, e_yy, e_zz, 2e_xy, 2e_yz, 2e_xz)?
