Theory Comput. 2009, 5, 3010–3021 Your options are: 1) ignore it and hope your numerics is OK, very well possible as you are using a small ADMM basis 2) go to a larger simulation box 3) Switch to the truncated PBE0 functional as described in the paper. Also have a look at the different integral screening options in order to make the calculation more stable. regards Juerg -------------------------------------------------------------- Juerg Hutter Phone : <a href="tel:%2B%2B41%2044%20635%204491" value="+41446354491">++41 44 635 4491</a> Institut für Chemie C FAX : <a href="tel:%2B%2B41%2044%20635%206838" value="+41446356838">++41 44 635 6838</a> Universität Zürich E-mail: <a href="mailto:hut...@chem.uzh.ch">hut...@chem.uzh.ch</a> Winterthurerstrasse 190 CH-8057 Zürich, Switzerland --------------------------------------------------------------- -----<a href="mailto:cp...@googlegroups.com">cp...@googlegroups.com</a> wrote: -----To: <a href="mailto:cp...@googlegroups.com">cp...@googlegroups.com</a> From: Apostolidou Christina Sent by: <a href="mailto:cp...@googlegroups.com">cp...@googlegroups.com</a> Date: 02/12/2016 10:03AM Subject: [CP2K:7424] I need help for HSE-functional calculation <div class="HOEnZb"><div class="h5"> Dear cp2k developers, Please help me.

(I tried it also with very small cutoff-radii) Nothing helps! Does anyone has another idea or knows this problem? Maybe I forgot one keyword which defines the cutoff-radius? I need to take the HSE06 functional because I need the screened exchange in combination with the MIC in order to calculate my system as a condensed phase. Thank you!
