Dear Leili,<div><br /></div><div>There is one solution to suggest. We have modified the "vibrational_analysis.F" file a little bit to specify a range of atoms to be shifted. By dividing the full range into several parts, it is feasible to calculate all forces by parts and then gather them to reconstruct the full Hessian and diagonalise it afterwards. If you like we could send you two source files to recompile the cp2k.popt. </div><div>Which version of cp2k do you use? </div><div><br /></div><div>Best regards,</div><div>Mikhail </div><div><br /><br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Sunday, December 31, 2023 at 9:24:27 PM UTC+1 Leili Rassouli 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;">Hi Eric,<br><br>I've faced a similar issue and was considering the approach you suggested.
