Hi Jurg,<div> </div><div>I guess it's a bug in the 2023.1 version then, because I also just tested the most recent pre-compiled binary (https://github.com/cp2k/cp2k/releases/download/v2023.1/cp2k-2023.1-Linux-gnu-x86_64.ssmp) and it still gives the same errors:</div><div> <img alt="pre-compiled binary.png" width="653px" height="783px" src="cid:ca59b28b-2811-462e-a7e9-76909694ce50" /></div><div> </div><div>Is a new version (2023.2) coming anytime soon perhaps? I tried compiling the trunk earlier this week after you fixed the CIF parser, both through cloning the Master from Git and using the tarball, but got errors during compilation... I'm going on vacation tomorrow but after I return I'll give it another try or if a newer version has released by then I'll try that and convince the HPC centre to install it.</div><div> </div><div>Best,</div><div>Léon</div><div> </div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday, 5 July 2023 at 15:03:44 UTC+2 Jürg Hutter wrote: </div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hi it works for me (CP2K Trunk version) Precond_solver : DEFAULT stepsize : 0.08000000 energy_gap : 0.08000000 eps_taylor : 0.10000E-15 max_taylor : 4 ----------------------------------- OT --------------------------------------- Step Update method Time Convergence Total energy Change ------------------------------------------------------------------------------ 1 OT DIIS 0.80E-01 7.1 0.10459074 -83.0126092838 -8.30E+01 2 OT DIIS 0.80E-01 7.0 0.07934045 -85.4719301173 -2.46E+00 3 OT DIIS 0.80E-01 7.3 0.04237559 -86.5088026249 -1.04E+00 4 OT DIIS 0.80E-01 7.3 0.02451275 -87.1588661747 -6.50E-01 5 OT DIIS 0.80E-01 7.3 0.01463005 -87.2604337873 -1.02E-01 6 OT DIIS 0.80E-01 7.3 0.00701148 -87.3511713376 -9.07E-02 7 OT DIIS 0.80E-01 7.3 0.00477888 -87.3692546957 -1.81E-02 8 OT DIIS 0.80E-01 7.3 0.00289219 -87.3773030540 -8.05E-03 This is running your input (removed the tabs and changed the file path). regards JH ________________________________________ From: <a href data-email-masked rel="nofollow">cp...@googlegroups.com</a> <<a href data-email-masked rel="nofollow">cp...@googlegroups.com</a>> on behalf of Léon Luntadila Lufungula <<a href data-email-masked rel="nofollow">Leon.luntad...@uantwerpen.be</a>> Sent: Wednesday, July 5, 2023 2:57 PM To: cp2k Subject: Re: [CP2K:19064] Unexpected 0D wavelet errors at large vacuum Just now, I also let CP2K print the atomic coordinates and the cell information so that I could visualize it in VMD to see if perhaps something goes wrong with reading in the structure. However, as you can see below, there is nothing wrong with the structure and there is ample vacuum space for the wavelet solver to work without throwing errors. I really don't understand how these errors occur for a structure which is essentially "over-qualified" for the wavelet method with 10 Å vacuum on all sides... Is this perhaps a bug in the code behind the wavelet solver?

I tried using it to calculate the energy of an isolated molecule and noticed some weird behaviour regarding the vacuum padding. At 2.5 Å vacuum around the molecule, I got an error saying "density non-zero on the edges of the unit cell: wrong results in WAVELET solver", so I increased the vacuum to 5 Å and this suppressed the error message. I wanted to see the effect of the vacuum on the energy so I also increased the vacuum to compare the energies. At 7.5 Å it all worked as expected, but then at 10 Å I again get errors stating that the density is non-zero at the edges, even when I include CENTER_COORDINATES. Can someone explain why this is happening? It seems very counterintuitive as it is exactly the same molecule and the only difference is that the vacuum padding around the molecule has increased... The outputs for 5, 7.5 and 10 Å are in attachment. The one with 2.5 Å, I seem to have deleted already as it resulting in the errors stated above.
