About This Product

■Product overview

WIEN2k is a solid-state electronic structure calculation program using density functional theory (DFT) developed at the Vienna University of Technology in Austria. Highly accurate band structure calculations are possible by adopting the (L) APW+lo method, which is a linearized extended plane wave method with extended local orbits, without using a spherically symmetric approximate potential shape. In addition, improved versions of spin local density approximation (LDA) or generalized density gradient approximation (GGA) can be used in DFT calculations, and all-electron calculations that take relativistic effects into account are also possible. Many other features are also available. The latest version is WIEN2k_18.2.

■Special notes

Starting from 9.1, MPI_LAPW using fftw2 has been enhanced. It is updated irregularly, about four times a year. Versions earlier than 8.2 are not compatible with Intel compiler 10.0 or later. It has been modified quite a bit.

■init_lapw

The most notable change is that init_lapw asks what to do with spin. When calculating in the same way as up to 08.3, select non magnetic, over right is y/N, and default is N, but select Y. If the struct file up to 08.3 was not overwritten to the 09.2 struct file using init_lapw, a fault would occur with run_lapw up to 09.2, but it now works with WIEN2k_10.1.
