Demeter

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

An application for data analysis of X-ray absorption fine structure (XAFS). Experimental data of XAFS can be analyzed by various analysis methods. This application supports various analysis functions (high-speed Fourier analysis, fitting in a radial coordinate or k-space, data plotting, etc.) based on IFEFFIT, and includes useful graphical user interface (GUI).

DFTB+

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

An application for quantum chemical calculation based on DFTB (Density Functional based Tight Binding). This application performs structure
optimization and molecular dynamics by the DFTB force field as well as ordinary energy calculation, and implements parallel computing by OpenMP. A tool for visualization of molecular orbitals and an extended versions supporting MPI parallel computation or electron transport calculation by the nonequilibrium Green’s function method are also
available.

DISCUS

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

An open source application to simulate crystal structures and to calculate and refine against diffraction pattern and the pair distribution function. A special emphasis placed is on the simulation of materials with disorder and the package provides many tools to create and distribute defects throughout the crystal. Another strong feature is the simulation of nanoparticles.

DMOL3

  • Level of openness 0 ☆☆☆
  • Document quality 3 ★★★

An application for first-principles calculation based on density functional theory. This application is included in Material Sudio, and can evaluate electronic states and properties of various physical systems such as molecules, atomic clusters, crystals, and solid surfaces based on the all-electron method and the pseudopotential method. It can also be applied to evaluation of the chemical reaction such as catalysis and combustion reaction, and is optimized for large-scale parallel computing.
