The local Hamiltonian is now output after the density matrix.
This is mainly needed for debug purposes. At a later stage the
output should be better formatted and controlled.
At the main SC script 'sc_dmft.py' requires importing a user DMFT
script as a module. Ideally, this should be implemented in a different
way so that the user script imports a function from the self-consistent
script.
Noramlly, the Fermi energy is read from DOSCAR. However, this does
not work in case of a self-consistent calculation in which DOSCAR
is not written between iterations. One of the options is
to modify slightly the output to LOCPROJ and add EFERMI to the
first line.
Since 'n_orbitals' can be a 2D array in case of spin-polarized
calculations, one should use 'numpy.max' instead of 'max' to
extract the maximum number of bands.
In the new version of VASP LOCPROJ contains the eigenvalues and
Fermi weights. Also, during a charge self-consistency calculation
the file EIGENVAL is not written at intermediate iterations. It is,
thus, preferential to use LOCPROJ to get the named data.
At the moment, EIGENVAL will still be used if it is complete but
in the future this dependence should be removed completely.
The band indices should be converted to Fortran convention,
i.e. starting from 1, in the output files because the are
used in the density matrix file which is read by a Fortran code.
The format of LOCPROJ has been modified again (in VASP 5.4.2
build from Dec 02, 2015).
Now, there is an additional line before each projector block
providing the spin, k-, and band indices, as well as
eigenvalues and Fermi weights.
Scripts 'run_plovasp.sh' have been replaced by a template in which
the path must be set by the user.
Also, .gitignore has been added to example 'lunio3'.
It was incorrect to ascribe VASP atomic sort to corr_shell['sort'],
the latter having a different meaning. According to the terminology of
Wien2k a sort determines an equivalence class of atoms.
Since the implementation at the moment does not support symmetries
the atom index is now used as a 'sort' index to make sure that all shells
remain inequivalent.
The files from the original vasp-interface repository are reshuffled in
accord with the directory structure of dft_tools. Some of the directories,
such as 'test' (unit tests for the interface), 'examples' (simple examples for
the development purposes) are temporarily placed into 'python/vasp' directory
to avoid confusion with integral tests and examples of dft_tools.
Import of 'json' is fixed to conform python distributions without
'simplejson'.
Also, the full path is used for 'converter_tools' for the moment while
'vasp_converter' is not part of 'dft_tools'.
It seems that not all distributions of python come with a 'simplejson' module.
Now, if this module is not found the import falls back to module 'json'.
At the moment, symmetries are not supported by the interface.
Instead, some dummy parameters are generated and the symmetry is turned off.
'misc_input' is only partially implemented because it contains
some data which is not required for the correct functioning of DftTools.
This preliminary version is untested and might not even run.
Here, almost all relevant input (apart from symmetries and miscellaneous)
is implemented and conventions adpoted in DftTools are accomodated.
