Last official stable release:

• DFTB+ 1.2

The DFTB+ package depends on external libraries. Those, which are usually not available in standard scientific computing environments, are distributed together with the source code of DFTB+. Currently, this is the library:

• xmlf90 (directory: ext_xmlf90)

The terms and conditions for the redistribution of this library is specified by its own licence (found in the appropriate subdirectory) and not by the DFTB+ licence.

The DFTB+ code needs parameterisation data (Slater-Koster files) in order to perform calculations. These parameters are not distributed with the code.

You can download the Slater-Koster files from dftb.org. The Slater-Koster files are distributed under a different licence  from DFTB+, so you will have to sign a separate licence agreement to obtain these files. Please note that your account to download parameters at the dftb.org site is separate to any account you may have at dftb-plus.info.
