Welcome to gpaw-tools

gpaw-tools is a collection of python scripts that use ASE and GPAW for performing Density Functional Theory (DFT) calculations. Its aim is to lower the entry barrier and to provide an easy-to-use command line and graphical user interfaces for GPAW. It is mostly written for new DFT users who are running codes on their own PCs or on small group clusters.

gpaw-tools have:

  1. A force-field quick optimization script for preliminary calculations using ASAP3/OpenKIM potentials.
  2. script for transform CIF files to ASE’s own Atoms object.
  3. To choose better cut off energy, lattice parameter and k points, there are 4 scripts called,, and
  4. The main solver script which can be run in PW (also with GW and EXX) or LCAO mode. It can do structure optimization, Equation of State and elastic tensor calculations, can use several different XCs (also hybird XCs), can do spin-polarized calculations, can calculate, draw and save tidily DOS and band structures, can calculate and save all-electron densities and can calculate optical properties (RPA and BSE) in a very simple and organized way.
  5. A simple Graphical User Interface (GUI) for (and also you may say that GUI for GPAW) which is called

Please do not forget that, gpaw-tools is a UI/GUI software. For the main DFT calculations, it uses ASE and GPAW. It also uses Elastic python package for elastic tensor solutions and ASAP with KIM database for interatomic interaction calculations. Therefore, you must know what you use, and cite them properly. Here, the basic citation information of each packages are given. There are many other packages needed to be cited. With GPAW, you may needed to cite LibXC or cite for LCAO, TDDFT, lineer-response calculations. Please visit their pages for many other citation possibilities.
