[Pw_forum] Fixed volume in high pressure calculations

[Wilfredo Ibarra Hernández]

Dear all

I'm relativity new using QE, I'm working with system under pressure, and I
want to know if it's possible relax the cell parameters but with fixed
volume.

I mean, I want relax the lattice parameters and the atomic positions, but
for a given volume value.

Thanks to all
