one question about 'Pstress'

#1 Post by zyang » Sat Aug 28, 2010 10:16 pm

Hi, I used 'Pstress' in INCAR to add hydrostatic pressure to a system. Can someone explain how to carry out it in detail?

1) before add 'Pstree' in INCAR, make sure the stress tensor is accurate. Set PREC=Accurate and increase the cutoff energy until you get small Pulay stresses.
2)Specify your external pressure using the Pstress tag while keeping the high ENCUT value and PREC = Accurate.
