BASIS_SET DZVP-GTH
POTENTIAL GTH-PADE

The PP GTH-PADE is sufficient to test the code, but obviously not suited to work with the M06-2X functional in a production run.

Matthias,

What basis set and potential did you use for the M06-2X GPW calculations?

Thanks,
Stacey

Hi

wrong numbers are obtained for mGGAs (like M06-2X) with GAPW, which is mandatory for all-electron calculations. The mGGA results, including M06-2X, using GPW are correct:

I'm guessing I probably shouldn't use the M06-2X functional for anything right now or at least until why the energy discrepancy is figured out in the meta functionals?

Hi Matthias



thank you. Can I ask you to run the same debug run for M06L and TPSS, two other meta functionals?

 Hi Jürg



 Unfortunately, there seems to be more than the 5d/6d difference when using the M06-2X functional. A comparison of the H2O structures relaxed with 6-31G** using BLYP, HF, B3LYP, and M06-2X reveals indeed a much larger difference for M06-2X:



      H2O/6-31G**

         CCCBDB

            CP2K

      BLYP

     -76.398885

      -76.396840

      HF

     -76.023615

      -76.023047

      B3LYP

     -76.419737

      -76.418114

      M06-2X

     -76.383939

      -76.378



 Moreover, the GEO_OPT run with M06-2X shows difference in the OH bonds which indicates wrong forces and indeed a DEBUG run reveals that there exists a problem related to M06-2X using the XC section as suggested:

*******************************************************************************



 A debug run with B3LYP works fine with errors of only 0.01%.



 So there is either an input error (&XC section with M06-2X) or a bug in CP2K (or libxc).



 Best regards



 Matthias

 Hi



 so as I said, the basis sets are different and that makes the results different.

 Hi Prof Hutter,



 Here's from CP2K

Total number of            - Atomic kinds:                                   2

                              - Atoms:                                          3

                              - Shell sets:                                    10

                              - Shells:                                        12

                              - Primitive Cartesian functions:                 21

                              - Cartesian basis functions:                     25

                              - Spherical basis functions:                     24



 This is from Gaussian

Standard basis: 6-31G(d,p) (6D, 7F)

     25 basis functions,    42 primitive gaussians,    25 cartesian basis functions

Hi

check the number of basis functions. Part or hopefully all of the energy difference is from the (6d) default in Gaussian.

 CP2K uses spherical functions only.

 Hello,



 The water energy at the M06-2X/6-31G** level is quite different when compared to Gaussian and the CCCBDB.



 Gaussian: -76.3831231205 Ha (#n M062X/6-31G** NoSymm SCF=(XQC, maxconventionalcycles=30) Int=UltraFine SP)

 CCCBDB:   -76.383939 Ha (https://cccbdb.nist.gov/energy3x.asp?method=58&basis=3&charge=0)

 CP2K:        -76.401243254272231Ha



 Anyone have any ideas on what settings need to be modified or can CP2K match that energy?
