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 3000 user groups and has about 12000 citations on Google scholar (Blaha WIEN2k).
This new lo (denoted with lower case to distinguish it from the LO given above) looks almost like the old ``LAPW''-basis set, but here the Alm and Blm do not depend on kn and are determined by the requirement that the lo is zero at the sphere boundary and normalized.
The forces at the atoms are calculated according to Yu et al (91). For the implementation of this formalism in WIEN see Kohler et al (94) and Madsen et al. 2001. An alternative formulation by Soler and Williams (89) has also been tested and found to be equivalent, both in computationally efficiency and numerical accuracy and the respective code is available from M.Fähnle (Krimmel et al 94).
