VASP 6.2.0: How to use DFTD4?

#1 Post by thda0531 » Fri Feb 12, 2021 9:43 am

Hi VASP-forums followers,

due to the release-notes of VASP 6.2.0 on the download-page the semi-empirical
vDW correction DFTD4 was implemented.

I can't find any description about DFTD4 and its usage in the VASP-wiki.
Will the wiki be updated soon?
Can somebody give me some hints, please?

Thank you in advance.

To use DFTD4 you need to download and compile the code from their website
Then you add a -DDFTD4 preprocessor option to your makefile.include and modify link and include path adding the path to your installation of DFTD4.

When that works you can activate it by setting IVDW = 13.
