Hi

you can used the same data file for both types of damping,
original and BJ. The file is provided with the CP2K distribution
in the data directoty.

      &vdW_POTENTIAL
         DISPERSION_FUNCTIONAL PAIR_POTENTIAL
         &PAIR_POTENTIAL
            TYPE DFTD3(BJ)
            CALCULATE_C9_TERM .TRUE.
            REFERENCE_C9_TERM .TRUE.
            LONG_RANGE_CORRECTION .TRUE.
            PARAMETER_FILE_NAME dftd3.dat
            REFERENCE_FUNCTIONAL PBE
            R_CUTOFF 15.
         &END PAIR_POTENTIAL
      &END vdW_POTENTIAL

regards

Juerg

Hello,
There was some problems regarding having cp2k version 3 working however now I am having different problems running the dtfd3bj jobs. I have download the files from http://www.thch.uni-bonn.de/tc/downloads/DFT-D3/functionalsbj.html to use these parameters however I am not sure what to put in the code as the actual parameter_file_name as the download is a zip file containing many coord files and a reference.dat that is a fortram program. When I attempted to use the reference file as the parameter file an error that the file could not be found.
Does anyone who's used bj damping know how this parameter file works or has an alternate parameter file I could use with the PBE functional?
Thanks, Richard Edwards

Yes thank you. The server I was using had the default set to use version 2.4 but 3.0 is available to use with some permissions. I will try to use this and post again if I have an issues.
Thanks again, Richard Edwards

I have been working with small (20-40 atom) quantum dots and am trying to see at what temperature the conformation is stable. Without including dispersion forces the structures were stable above 300K but with DFTD3 the structure began to break at much lower temperatures ~125K. To get a more accurate idea of the working temperature I attempted to use DFTD3(BJ) however when I used the parameters retrieved from the cp2k manual site and the following input code section:
     &XC_FUNCTIONAL PBE      &END XC_FUNCTIONAL       &VDW_POTENTIAL          POTENTIAL_TYPE PAIR_POTENTIAL          &PAIR_POTENTIAL             TYPE DFTD3(BJ)             REFERENCE_FUNCTIONAL PBE             PARAMETER_FILE_NAME /bg01/homescinet/i/ihamilto/edwa3980/DFTD3BJ_Parameters/reference.dat             R_CUTOFF 15          &END       &ENDI got the following output file:

Does anyone know why it does not seem to recognize the DFTD3BJ type command? Or has anyone set up these calculations that can provide any insight to help me run these.
