[Wien] Stress

[David Tompsett]

Dear All,

Has anyone ever tried to implement the calculation of the stress tensor into
Wien? Is there something in the method that prevents its calculation?

I read the Nielsen PRB 32, 3780 (1985) where stress calculation is described
for local functionals. There are 5 contributions in equation 30 of that
paper. Is any in particular difficult for LAPW methods?

Many thanks,
David Tompsett.
