[Pw_forum] ambiguous results with vc-relax

[jia chen]

sorry for interrupting you guys, I didn't follow the whole post before.
Pressure calculations need very high ecutoff. And,according to my
experience, vc-relax is supposed to be slow. So, I usually avoid vc-relax if
possible... Last but not least, I am a student, maybe very wrong. Have a
good day.
