Dear all, I know If I set tstress=.true. the stress tensor will be computed and printed. but What's the kind of the Stress Tensor QE dose print? for example Cauchy, true, Kirchhoff, PK2, ... I am trying to calculate second Piola–Kirchhoff (PK2) stresses with QE. Any suggestions or comments are appreciated.
