<div dir="ltr">Hello,<div><br></div><div>Perhaps the talk on Geometry and Cell Optimization by Matt Watkins from the last cp2k tutorial would be a good place to start.</div><div> <a href="https://www.cp2k.org/events:2015_cecam_tutorial:index">https://www.cp2k.org/events:2015_cecam_tutorial:index</a></div><div><br></div><div>However, if you are planning to study an ethanol dimer, you'll likely want to do that in the gas phase, i.e. with vacuum on all sides of the molecule. Simply choose a large enough cubic or orthorhombic box, sophisticated tuning of the cell parameter should not be necessary.</div><div><br></div><div>Hope that helps,</div><div>Ralph</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jun 1, 2016 at 3:07 PM, josué Maya <span dir="ltr"><<a href="mailto:maya...@gmail.com" target="_blank">maya...@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<blockquote class="gmail_quote" style="margin:0;margin-left:0.8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><br></div><div>As you are talking about cell optimisation, please can you explain to me how I can do a Cell optimization ?
