<div> Dear all</div>
<div> Could someone tell me the difference between vc-relax and relax ? What are the functions of them . In what conditions to use them ?</div>
<div> </div></blockquote><div><br>PLEASE READ THE DOCUMENTATION, it is in espresso-whateverversion/Doc/INPUT_PW<br><br>Both can relax the ionic positions until each and every ion feel zero forces (Actually is not zero but a minimum force that you define inside &control)<br>
<br>"vc" in vc-relax stands for variable cell, which means that the cell is also relaxed towards a target pressure (read &cell in the documentation) <br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
