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
