<div>Hello everyone,</div><div><br></div><div>I'm trying to perform a geometry optimization of an isolated molecule composed of 27 atoms and I get the warning</div><div><br></div><div>*** WARNING in pw/ps_wavelet_methods.F:241 :: Density non-zero on the ***<br>*** edges of the unit cell: wrong results in WAVELET solver ***</div><div><br></div><div>followed by " CPASSERT failed, mp2_ri_2c.F:1345 ".</div><div>I have looked at other threads such as</div><div>https://groups.google.com/g/cp2k/c/J3WxEhnuNOY/m/lJ1GMSYyAQAJ</div><div>https://groups.google.com/g/cp2k/c/g4eXkddU2TM/m/U72NxzdpBQAJ</div><div>but they don't solve my problem.</div><div><br></div><div>I attach my input and (part of the) output files: I'm using double hybrid DSD-PBEP86 (as detailed in https://pubs.rsc.org/en/content/articlelanding/2011/cp/c1cp22592h) which involves performing some MP2 calculations. You can see in the input that I have reduced the accuracy of this section (I get "out of memory" errors otherwise): could this be the cause of the error?<br><br>Thanks for the help!</div><div>Sincerely,</div><div>Paolo<br></div>
