OCTA

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

OCTA is an integrated simulation system for soft materials developed by the joint project of industry and academia funded by Ministry of Economy, Trade and Industry(METI), Japan. OCTA consists of four simulation engines named COGNAC(Molecular dynamics simulation), PASTA(rheology simulation), SUSHI(mean field theory), MUFFIN(continuum theory) and a simulation platform (GOURMET).

Octopus

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

An open-source application for first-principles calculation based on pseudo- potential and real-space basis. It performs electronic-state calculation such as band calculation of solids and structure optimization for a variety of physical systems. The method of time-dependent density functional theory (TDDFT) is implemented, which allows simulation of dynamical phenomena with real-time evolution of electronic states, such as chemical reaction and electronic response to time-dependent external fields. Comes with detailed tutorials and comprehensive manuals.

ONETEP

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

An application for first-principles calculation based on the order-N method. This application can perform electronic-state calculation and band calculation for various physical systems. It supports the DFT+U method, the time-dependent DFT method, molecular dynamics, etc., and can also treat van der Waals forces and phonons. By using support applications, generation of input files, transformation between different file formats, and analysis of numerical results can be performed.

OVITO

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

An open-source application for visualization of atoms and molecules developed for molecular dynamics. This application supports a number of input file formats for molecular configration, and can perform visualization of three-dimensional atom configration as well as creation of a animation. The main feature of this application is that various useful analysis tools can be used by intuitive control of a graphical user interface (GUI).
