General remarks on WIEN2k
WIEN2k consists of many independent Fortran90 programs, which are linked
together via C-shell scripts. You can run WIEN2k using any www-browser and the
w2web interface, but also by typing short specialized commands.
The main tasks are:
- Define your structure (cif-file import, spacegroup support, symmetry
dedection)
- initialize (semi-automatic guided input generation)
- run scf-cycle (with/without simultaneous optimization of atomic positions)
- Calculate some properties ("Guided Tasks" in w2web)
- write a publication (NOT yet supported in w2web, you must do it yourself)
You may get a first impression by browsing the "Quick-Start" section of our Usersguide.
Calculated properties
- Energy bands and density of states
- electron densities and spin densities, x-ray structure factors
- Baders's "atoms-in-molecule" concept
- total energy, forces, equilibrium geometries, structure optimization,
molecular dynamics
- Phonons, with an interface to K.Parlinski's PHONON program
- electric field gradients, isomer shifts, hyperfine fields
- spin-polarization (ferro- or antiferromagnetic structures), spin-orbit
coupling
- x-ray emission and absorption spectra, electron energy loss spectra
- optical properties
- fermi surfaces
- LDA, GGA, meta-GGA, LDA+U, orbital polarization
- centro- or non-centrosymmetric cells, all 230 spacegroups built in
