HI Alexandra,<div><br></div><div>Have you considered trying DFTB+ (https://dftbplus.org/) ? It has the xTB Hamiltonians and they have precompiled binaries which are super easy to use.</div><div><br></div><div>I've used it a few times for some periodic calculations and it works nicely.</div><div><br></div><div> Cheers!</div><div>Frank<br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Friday, September 30, 2022 at 4:00:37 AM UTC-4 Alexandra Tsybizova wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Dear cp2k community, <div><br></div><div>I have been experiencing weird errors when I try to run md simulations with cp2k, when I use xtb method. The calculation seems to run fine for the first 130 steps or so, and then abruptly crashes with a signal 6 (SIGABRT). In the past, I used similar inputs to run dft trajectories, and they all finished normally. Browsing this forum I found that similar behavior (termination with a signal 6 (SIGABRT)) was reported by one of the users previously, (<a href="https://groups.google.com/g/cp2k/c/QWeC0KAgr2A" target="_blank" rel="nofollow" data-saferedirecturl="https://www.google.com/url?hl=en&q=https://groups.google.com/g/cp2k/c/QWeC0KAgr2A&source=gmail&ust=1664625350608000&usg=AOvVaw0FYOFHG2U0cXSuwns8KQ-6">https://groups.google.com/g/cp2k/c/QWeC0KAgr2A</a>) and in that case was solved by removing a duplicate line from the input. I checked my input for duplicate lines and could not find any, however. Could you help me identify where the problem might be? </div><div><br></div><div>Thank you and best regards,</div><div><br></div><div>Alexandra </div></blockquote></div>
