Wien2k使用密度泛函理论计算固体的电子结构。它基于键结构计算准确的方案——完全势能（线性）增广平面波((L)APW)+局域轨道(lo)方法。在密度泛函中可以使用局域（自旋）密度近似(LDA)或广义梯度近似(GGA)。它已被近3000个用户组授权，在Google scholar上有大约12000个引用。
Wien2k包含很多Frotran90立程序，通过C-脚本连接到一起。您不仅可以在任何浏览器和w2web界面上运行Wien2k,也可以输入的短命令来运行。
系统要求
The program is written in FORTRAN90 and runs under Unix on practically all platforms (Linux-PCs, IBM RS6000, HP, SGI, COMPAC-alpha, SUNs).
The most efficient platform changes rapidly with time, although we expect that the best price/performance ratio will also in future be some Linux PC based on an Intel architecture (for current benchmark tests click here ). Install the Intel ifort compiler + Intels mkl-libarary (there is a free non-commercial version or the goto-blas .
It requires at least 128 MB memory for small systems (to about 10 atoms per unit cell) or more for larger systems. At present we recommend a multicore CPU with 1-2GB memory / core and twice as much swap space (don't forget to configure the latter!). We have treated systems up to 100 atoms per unit cell on workstations with large memory (1-2 GB) and with more than 1000 atoms/cell on clusters with 64 - 1024 cores and fast network. 1 GB (or 10-1000GB for large cases) of disk space is required.
k-point parallelization is possible and highly efficient on a cluster of PCs (Gbit network is enough), provided a common NFS-file system is available and login (rsh or ssh) is configured properly.
A fine grain parallelization for a single k-point is also available. It requires fast communication (shared memory or fast networks (Infiniband), Gb Ethernet is not really sufficient), MPI, FFTW and Scalapack.
In order to use all options (including the graphical user interface or XCRYSDEN) the following public domain packages must be installed on your system: ghostview (+png support), gnuplot (+png support), acroread (or similar),(Netscape), Perl.
and the coefficients cn are determined by the Rayleigh-Ritz variational principle. The convergence of this basis set is controlled by a cutoff parameter RmtKmax= 6 - 9, where Rmt is the smallest atomic sphere radius in the unit cell and Kmax is the magnitude of the largest K vector.

In the last years it became a tradition to have at least one "WIEN-workshop" every year, where new and experienced users can learn more about the code, get intensive hands-on training, interchange ideas and share experiences.

主要功能
定义结构（CIF文件导入、空间组支持、对称性检测）
初始化（半自动引导输入生成）
运行scf-cycle（同时或不同时优化原子位置）
计算一些参数（w2web中的Guided Tasks）
编写出版物（w2web中不支持，需要自己编写）
In the last years it became a tradition to have at least one "WIEN-workshop" every year, where new and experienced users can learn more about the code, get intensive hands-on training, interchange ideas and share experiences.
This year the
26. WIEN2k workshop
will be held in
Vienna, Austria,
as Satellite meeting to the 32nd European Crystallographic Meeting (ECM32).
13. - 17. August 2019
