The program package 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. It has been licensed by more than 2000 user groups.

The current version is WIEN2k_13.1 and was released on 25.June 2013. Version 13.1 is a very important update, fixing some bugs and introducing several new features. Upgrading is highly recommended.

We would like to announce the 21. WIEN2k workshop held at Institut des Materiaux Jean Rouxel (IMN), Nantes, France. 2. - 5. July 2014 More details and registration will follow later. In addition to the WIEN2k workshop there will be a connected conference, which we highly recommend: ICAMM 2014 (3rd International Conference on Advanced Materials Modelling) 7. - 9. July 2014

We proudly announce that the 2000th license of WIEN2k was granted free of charge to Prof. Gopalan Srinivasan, Oakland University, USA We would also like to take the opportunity to thank all WIEN2k users for their continuous interest and the lively discussions on the WIEN2k-mailinglist. In particular we want to acknowledge all who have contributed to this package. This international cooperation is largely responsible for the success of WIEN2k.
