Download WIEN2k_21.1 electronic structure calculations DFT

WIEN2k  allows to perform electronic structure calculations of solids using density functional theory (DFT). It is based on the full-potential (linearized) augmented plane-wave ((L)APW) + local orbitals (lo) method, one among the most accurate schemes for band structure calculations. WIEN2k is an all-electron scheme including relativistic effects and has many features.

  • centro- or non-centrosymmetric cells (mode), all 230 spacegroups built in
  • spin-polarization (ferro- or antiferromagnetic structures), spin-orbit coupling
  • sequential mode, k-parallel mode (without MPI, slow network with common NFS), massively parallel MPI mode (shared memory or Infiniband)
  • Energy bands and density of states
