i-PI

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

i-PI is a universal force engine interface written in Python, designed to be used together with an ab-initio (or force-field based) evaluation of the interactions between the atoms. This application includes a large number of sophisticated methods such as replica exchange molecular dynamics (REMD) and path integral molecular dynamics (PIMD). Inter-atomic forces can be computed by using external codes such as CP2K, Quantum ESPRESSO and LAMMPS.

TeNeS

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

A solver program for two dimensional quantum lattice model based on a projected entangled pair state wavefunction and the corner transfer matrix renormalization group method.
This works on a massively parallel machine because tensor operations are OpenMP/MPI parallelized.

Molden

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An open-source application for pre- and post-processing for quantum chemistry calculation. This application can handle outputs from Gaussian, GAMESS, and MOPAC as well as the result of other applications via the Molden format. It supports many graphical interfaces such as Postscript, XWindows, VRML, and OpenGL, and performs visualization of molecular orbitals and electron density. It also produces animation videos of molecular vibration.

DC

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An electronic state solver distributed with GAMESS, the quantum chemical (QM) calculation software. Combining energy density analysis and Divide-and-Conquer (DC) method, accurate QM calculation with electronic correlation is solved in a short time. Highly accurate QM calculations for many-atom/nano-scale material can be solved when run on a high performance super computer.

NAP

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

A group of applications that perform molecular dynamics, hybrid quantum/classical mechanical simulation, search of chemical reaction path by the nudged elastic band method, and potential parameter fitting. The molecular dynamics code includes interatomic potentials for several metals and semiconductors, and is capable of parallel computation based of spatial decomposition.

OACIS

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An open-source framework for execution management of numerical simulation. By registering target simulators, information at the time of execution (parameters, date and time, hostname, version of simulators, etc.) and calculation results are saved automatically on database. Job submission and browse of job status can be performed efficiently from web browsers.

TRIQS/DFT tools

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An interface tool for combining first-principles calculation based on density functional theory (DFT) and TRIQS, the application for dynamical mean-field theory (DMFT). By combining Wien2k and TRIQS, self-consistent DFT+DMFT calculation can be realized by this tool. One-shot DFT+DMFT calculation using band structures obtained by other first-principles applications is also possible.

VisBAR

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆
A set of Python scripts for post-simulation data analysis of large-scale electronic state calculations. Currently the open script is ‘VisBAR Wave Batch’ that visualizes many wavefunctions, as isosurfaces, simultaneously. The script generates picture files in PNG and other formats from grid data files in the Gaussian cube format. Many data files can be treated in parallelism by MPI.
