BEEF Functional Software

Espresso with BEEF

Johannes Voss has created a version of Quantum Espresso that includes the BEEF functional. Installation instructions can be found here:

https://github.com/vossjo/ase-espresso/wiki

libbeef Library

The latest development version can be obtained with this command:

svn co svn://suncatls1.slac.stanford.edu/beef/trunk beef

Installation instructions for the different versions are contained in the README file in the above downloadable files.

VASP Patches

Johannes has also created patch files for various versions of VASP that allow BEEF to be used there. These can be downloaded from here:

Within the VASP directory containing the fortran files:

patch -p1 < vasp.5.3.beef.diff

Then edit your VASP Makefile to add the following after the LIB variable is defined:

LIB+= -Lpathtobeeflibrary/lib -lbeef

Then build VASP as usual. The following lines should be appended to your .INCAR file to run a BEEF calculation (the last line is optional and triggers the calculation of ensemble energies for error estimation):

GGA = BF
LUSE_VDW = .TRUE.
Zab_VDW = -1.8867
LBEEFENS = .TRUE.
