Unsupported software goodies
©2001 by P. Blaha, K. Schwarz and J. Luitz
We link here to software (mainly developed by WIEN2k-users) which are either
distributed directly by the authors or which we distribute ourself, but the
software has (for one or the other reason) not been fully integrated into
Xcrysden by T.Kokalj. Visualization of
crystal structure, electron densitites, fermi surfaces. Highly recommended and
integrated into w2web.
Vesta by Fujio Izumi. A very nice and flexible visualization program of
crystal structures, can read case.struct files, edit structures, write cif-files, display arrows and polyhedra.
With wien2venus.py it can also visualize 3D densities/potentials as well as couloring isosurfaces by another quantity. Highly recommended .
free program for visualization and manipulation of
crystal structures under Windows. It can read/write wien2k struct files
directly and convert settings.
commercial program for visualization of
crystal structures under Windows and Mac. It can read wien2k struct files directly.
Spaghetti-primavera An alternative to
spaghetti, can produce multicolor plots indicating the band-character including
arbitrary combinations and several characters at once
(see Fig.2 of
PRL 101, 026406 (2008)), but
requires to understand some basic FORTRAN. Contributed by Maurits Haverkort (MPI Stuttgart).
Spaghetti-prima.py Same as above, but
with a very convenient Python-wrapper. It was developed by Elias Assmann
(email@example.com) and updated 16.Nov.2015).
a simple b/w interactive 2D-contour plot program (based on routines by K.Hermann,
modified by P.Blaha) which can read the WIEN2k case.rho files. Requires the
"pgplot"-library, which is included for 64-bit Suse-12.2, compiled with
gfortran and gcc. Useful tips for installing the pgplot-library can be found at
an interface package for making 2D fermi surface plots with
OPENDX (dx). (by Gavin Abo, firstname.lastname@example.org). Here is the pdf Users-guide.
a package for making grace files from data files (by Morteza
Jamal, email@example.com). Here is the pdf Users-guide.
JPlot (by Adlane SAYEDE,
code. It produces the same kind of plots (Density of States, Bandstructure,
Optical properties and Electron density plots) as the native WIEN2K (w2web)
interface but with no 3rd party program (i.e. gnuplot).
GAP2: GW with Augmented Planewaves by Hong Jiang.
This is a very accurate GW code based on WIEN2k, which allows to obtain fully converged
benchmark GW calculations. However, it requires large computational ressources.

O. Rubel (please cite: O. Rubel, A. Bokhanchuk, S. J. Ahmed, E. Assmann,
Physical Review B 90 (2014) 115202, ( http://arxiv.org/abs/1405.4218).
This software allows to unfold ("backfolding") the electronic band structure of supercell calculations for impurities/vacancies or magnetic superstructures.
Woptic by E. Assmann, P. Wissgottl (please cite: E. Assmann,
P. Wissgott, J. Kuneš, A. Toschi, P. Blaha, and K. Held: "woptic: optical
conductivity with Wannier functions and adaptive k-mesh
Physics Commun. 202, 1 (2016) or arXiv:1507.04881. ).
This software allows to calculate the optical conductivity, dc conductivity, and
thermopower in the Wien2k ecosystem. Woptic builds upon the optic and
wien2wannier modules of Wien2k,
combined with Wannier90 and (optionally) an external many-body
calculation, to work with the dipole matrix elements from optic in a
basis of maximally-localized Wannier functions.
Interesting features include:
* woptic can incorporate a local self-energy Σ(ω) from a many-body
calculation such as dynamical mean-field theory (DMFT)
* it employs an adaptive k-integration scheme to sample the Brillouin
* it uses the full dipole matrix elements, rotated to the Wannier
* transitions beyond the Wannier orbitals can be included in an

This software calculates crystal field parameters in rare-earth systems. It
requires wannier90 and Wien2Wannier (see above). You can download here the
usersguide (including a couple of
references), a quick-guide as well as a talk and a paper by P. Novak.
Triqs is a DMFT (Dynamical mean field theory) software for the description of
highly correlated materials. It includes an interface to WIEN2k.
DFT+eDMFT developed by Kristjan Haule at Rutgers University is a DMFT (Dynamical mean field theory) software for the description of
highly correlated materials based on WIEN2k. It has a very good documentation
and very interesting features including a total energy + forces for structure
optimization of highly correlated materials.
Phonon by K.Parlinski.
This software runs under Linux (or Windows) and allows to calculate phonons based on forces calculated by WIEN2k.
An interface to PHONON is included in WIEN2k.
PHONOPY by Atsushi Togo.
This package also provides the possibility to calculate phonons using WIEN2k
(see the most recent phonopy usersguide). Earlier PHONOPY versions would need
program scf2forces by Evgeniya Kabliman, which can create the required FORCE_SETS
file from a "symmetrized" WIEN2k supercell.(Even earlier versions of PHONOPY (before
0.9.4) used a different file-format and the file FORCES, which can be generated by
this interface ).
WIEN2PHON by G.Madsen.
These scripts provide an interface between WIEN2k and D.Alfe's PHON program, which, similarly to PHONON (see above) can calculate phonons using WIEN2k.
BoltzTraP2 by G.Madsen.
This program calculates semiclassical transport (thermoelectric
transport coefficients as functions of temperature and chemical potential in
the rigid-band picture) based on a smooth Fourier
interpolation of bands. It is the more modern implementation of the previous
SKEAF by P.M.C. Rourke.
This program extracts quantum oscillation
frequencies and effective masses from calculated Fermi surfaces stored
in the XCrysDen BXSF format (which can be produced by XCrysDen+Wien2k).

The NOMAD Repository was established to host, organize, and share materials data.
NOMAD copes with the increasing demand and requirement of storing scientific data and making them available for longer periods. This rule of good scientific practice is set by many funding agencies worldwide. NOMAD keeps scientific data for at least 10 years for free. NOMAD also facilitates research groups to share and exchange their results, inside a single group or between two or more, and to recall what was actually done some years ago.
Upload of data is possible without any barrier. Results are accepted in their raw format as produced by the underlying code. The only condition is that the list of authors is provided, and code and code version can be retrieved from the uploaded files. These data can be restricted to the owner or made available to other people (selected by the owner). They can be updated and downloaded at any time.

SRC_mpiutil by Laurence Marks (Lfirstname.lastname@example.org).
This package contains some utility programs (Machines2W) to generate a

submitted to queuing systems like PBS, SGE (sun-grid engine) or the Loadleveler".
