In this run, several tensors under #%% different boundary conditions are computed. They are respectly: relaxed ion #%% dielectric tensor, free-stress dielectric tensor; relaxed ion elastic #%% (and compliance) tensors under fixed-electric and under fixed- #%% displacement field boundary conditions; internal strain tensors ( #%% force response and displacement response); relaxed ion piezoelectric #%% tensors of several different definations (e, d, g, h tensors). #%% Please refer to Infos/Theory/vanderbilt-anaddb-notes.pdf for details. #%% In the previous version, only relaxed(clamped) ion dielectric, piezoelectric, #%% elastic tensors and internal strain tensors were computed. In this new version, #%% piezoelectric (d, g, h tensors), free-stress dielectric tensor, elastic #%% tensors at fixed displacement filed and elastic tensor with stress correction #%% are the new abilities of anaddb. #%% topics = Elastic #%%
