Welcome to gpaw-tools

gpaw-tools is a powerful and user-friendly UI/GUI tool for conducting Density Functional Theory (DFT) and molecular dynamics (MD) calculations. Our goal is to make DFT and MD calculations more accessible and easy to use for individuals and small groups, by providing a simple command-line interface and graphical user interface.

The gpaw-tools package is built on top of the ASE, ASAP3, KIM-API, PHONOPY, and GPAW libraries, which are well-established and widely used in the scientific community. It allows users to simulate the properties of materials, optimize structures, investigate chemical reactions and processes, and perform calculations on systems with a large number of atoms. With gpaw-tools, researchers, students, and engineers in a wide range of fields, including materials science, chemistry, physics, and engineering, can easily conduct DFT and MD calculations and explore the electronic, optical, and phonon structure of material systems. We are constantly working to improve and expand the capabilities of gpaw-tools, and we welcome feedback and contributions from the community.

gpaw-tools have:

  1. The main solver script can run in PW or LCAO mode. It can perform structure optimization, equation of state and elastic tensor calculations, and use several different XCs (as well as hybrid XCs) for spin-polarized DOS and band structure calculations, electron densities, phonon calculations, and optical properties (RPA and BSE). In addition to calculations, it can draw DOS and band structures, save all data, and figure in an ordered way.
  2. A force-field quick optimization script for MD calculations using ASAP3 and OpenKIM potentials.
  3. To choose better cut-off energy, lattice parameter, and k-points, there are 4 scripts called,, and
  4. A simple Graphical User Interface (GUI) for (and also you may say that GUI for GPAW) is called

Please do not forget that gpaw-tools is UI/GUI software. For the main DFT calculations, it uses ASE and GPAW. It also uses the Elastic python package for elastic tensor solutions and ASAP with the KIM database for interatomic interaction calculations and Phonopy for phonon calculations. Therefore, you must know what you use, and cite them properly. Here, the basic citation information of each package is given.


And for gpaw-tools usage, please use the following citation:

There are many other packages that need to be cited. With GPAW, you may need to cite LibXC or cite for LCAO, TDDFT, and linear-response calculations. Please visit their pages for many other citation possibilities. For more you can visit,, and
