Materials Project

A results database of first-principle calculation for material science. This database provides numerical data of crystal structures, band structures, thermodynamic quantities, phase diagrams, magnetic moments, and so on. This site is maintained by a research group of MIT, and has extensive data of materials related to lithium battery. In addition to a user interface based on web browsers, an http-based API is also provided to enable user-defined material screening. This database can be used without charge after registration.

MODYLAS

  • Level of openness 3 ★★★
  • Document quality 1 ★☆☆

MODYLAS is a highly parallelized general-purpose molecular dynamics (MD) simulation program appropriate for very large physical, chemical, and biological systems. It is equipped most standard MD techniques including free energy calculations based on thermodynamic integration method. Long-range forces are evaluated rigorously by the fast multipole method (FMM) without using the fast Fourier transform (FFT) in order to realize excellent scalability. The program enables investigations of large-scale real systems such as viruses, liposomes, assemblies of proteins and micelles, and polymers. It works on ordinary linux machines, too.

M2TD

  • Level of openness 1 ★☆☆
  • Document quality 1 ★☆☆

This software is for constructing inter-atomic force fields that mostly fit the results of ab-initio calculations, using multi-canonical molecular dynamic simulations. Various potential functions such as silicon, ionic crystal, and water have been pre-installed, and the user’s potential function can also be used. The default ab initio calculation solver is xTAPP and other calculation libraries are also applicable.

Mm2cML

  • Level of openness 0 ☆☆☆
  • Document quality 2 ★★☆

Mm2cML is a web application that structure files can be generated from molecular model images. By carrying out three-dimensional reconstruction using OpenMVG and OpenMVS from molecular model images photographed by smartphones or digital cameras, and arranging atoms on the basis of them, users can obtain structure files (CML format) usable for molecular simulation. The simulation can be carried out on the basis of the structure examined using the molecular model in the real world.

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.

Maxent

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

Tool for performing analytical continuation for many-body Green’s functions by using the maximum entropy method. From the data of the Green functions on the imaginary axis, users can obtain the values of the Green’s functions on the real axis. This tool supports the several different Green’s functions (Bozonic, Fermionic, anomalous, etc.).
