OpenMX Viewer (Open source package for Material eXplorer Viewer) is a web-based graphical user interface (GUI) program for visualization and analysis of crystalline and molecular structures.
XYZ, CIF, OpenMX input/output, md(molecular dynamics) files, the Gaussian cube format such as electron density and molecular orbitals can be visualized quickly by drag-and-drop, and it is easy to analyze static/dynamic structural properties conveniently in a web browser. Several basic functionalities such as analysis of Mulliken charges, molecular dynamics, geometry optimization and band structure are included.
Open source software package to visualize scientific/engineering data. This is provided as a GUI application based on X window system to move the camera, modify parameters, and play animation. This supports several data formats; CDF, NetCDF, and so on.
Ising model and QUBO heuristic optimization library. The core of the optimization is implemented in C++; it has a Python interface, therefore it can be easily written in Python.
OpenFFT is an open source parallel package for computing multi-dimensional Fast Fourier Transforms (3-D and 4-D FFTs) of both real and complex numbers of arbitrary input size. It originates from OpenMX (Open source package for Material eXplorer). OpenFFT adopts a communication-optimal domain decomposition method that is adaptive and capable of localizing data when transposing from one dimension to another for reducing the total volume of communication. It is written in C and MPI, with support for Fortran through the Fortran interface, and employs FFTW3 for computing 1-D FFTs.
An open-source multi-purpose application for simulation of fluids and continuous fields. This application can treat complex fluids including chemical reaction, turbulence, thermal condition, and combustion as well as thermal conduction of solids, stress fields, magnetohydrodynamics, and so on. It supports parallel computing, and also prepares pre- and post-processing functions. It is coded by C++ to keep high efficiency in development, debugging, and maintenance.
Open-source tools and a database for molecular simulation. Data of molecular models (interatomic potentials and force fields), result data of molecular simulation, and test tools can be downloaded freely. API (Application Programming Interface) for exchanging information between atomistic simulation codes and interatomic models is also provided.
OpenMX is a first-principles software based on the pseudo-atomic localized basis functions. It calculates electronic structure rapidly for a wide range of materials including crystals, interfaces, liquids, etc. It speedily provides molecular dynamics simulation and structural optimization of large-scale systems and also implements a hybrid parallelism. It is able to deal with non-collinear magnetism and non-equilibrium Green’s function calculations for electrical conductions.
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.
An open-source application for the phase-field simulations. This application treats many kinds of problems in materials science such as determination of phase diagrams, crystal growing, small structures accompanied by first-order transition, and so on. Its source code is open under the GPL, and is developed putting emphasis on its flexibility in the C++ language.
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).
