Dear all<br><br>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.<br><br>I mean, I want relax the lattice parameters and the atomic positions, but for a given volume value.<br>
<br>Thanks to all<br><br>Ibarra Hernŕndez Wilfredo<br>Master student<br>Cinvestav, unidad Qučretaro<br>Qučretaro, Mčxico.<br>
