[Pw_forum] Lower limit of target pressure

[Subhodip Chatterjee]

Dear PWSCF developers,

Is there any restriction in the code for the "press" (target pressure)
input?

I successfully get my vc-relax calculations converged to desired pressure
values as high as several terapascal, however, when I set a low enough
value, e.g. 1 bar (i.e. press = 0.001), the final pressure in the output
differs a lot!

Best regards
Subhodip
