B3LYP calculations start converging only when EPS_PGF_ORB is reduced to 1.0E-32 (as previously suggested in a CP2K thread). Below you will find the input for a B3LYP calculation that differs from a BLYP one only in the exchange-correlation functional and EPS_PGF_ORB. Minimal sample output is also provided for both BLYP and B3LYP.

Most people would use the corresponding BLYP PP in such a case (and also for all other elements in the calculation). The best choice for a basis set is the MOLOPT series. You can find them in BASIS_MOLOPT in tests/QS. Finally, you could generate your own (B3LYP) pseudos and basis sets using the atomic code that is part of CP2K. Some examples can be found in tests/ATOM. regards Juerg -------------------------------------------------------------- Juerg Hutter Phone : ++41 44 635 4491 Physical Chemistry Institute FAX : ++41 44 635 6838 University of Zurich E-mail: <a>hut...@pci.uzh.ch</a> Winterthurerstrasse 190 CH-8057 Zurich, Switzerland --------------------------------------------------------------- -----<a>cp...@googlegroups.com</a> wrote: ----- To: <a>cp...@googlegroups.com</a> From: Lavinia Sent by: <a>cp...@googlegroups.com</a> Date: 08/28/2012 05:18AM Subject: [CP2K:3995] GTH BLYP and B3LYP basis sets and pseudopotentials for Fe Dear GTH, I am preparing QM(DFT)/MM calculations for a chemical reaction catalyzed by an iron enzyme. I am interested in running the simulations both at BLYP and hybrid B3LYP level. While there is a Fe GTH optimized pseudopotential generated and available for the BLYP calculations in the CP2K database, there is no Fe basis set in the GTH_BASIS_SETS. Could you provide one? Can it be generated with the new ATOM BASIS_OPTIMIZATION codebase? Would you please address the same issue for B3LYP (BASIS/PSEUDOPOTENTIAL_OPTIMIZATION availability and accuracy)?
