[CP2K:5235] Re: Implementing new functionals

[hut... at chem.uzh.ch]

Hi

a few more points:
- if possible I would suggest to test the different parts of the
  functional individually (GGA + HFX + vdW)
- test first for the total energy using a simple system (He or Ne)
- remember that the VV10 part is in CP2K rVV10. In addition, this is
  only calculated for the 'soft' density in a GAPW calculation.
  You will not be able to compare total energies, only differences.

Hi again.

Well, maybe somehow apples and oranges are being compared?

I attach the PES I get for Ne dimer using Guassian 09 and the B97 functional (keyword B98, so possibly a revision?), with aug-cc-pVTZ basis (no BSSE correction applied).

I'll leave it for other more knowledgeable people to comment further.
