OVITO is a scientific data visualization and analysis software for atomistic simulation models in materials science and related physics and chemistry disciplines. OVITO is freely available for Windows, Linux, and macOS under an open-source license. It is being developed by Dr. Alexander Stukowski at the Materials Science Department of Darmstadt University of Technology, Germany.
The first version of OVITO was released in 2009 and has been described in a journal article. Today, OVITO has over 200,000 regular users from the computational physics, materials science and chemistry fields.
OVITO is a software for visualizing and analyzing output data from particle-based simulation models, notably molecular dynamics (MD) simulations of solid-state materials. Its main focus is on large simulation models based on classical potentials (103 - 108 atoms). Some noteworthy program features are:
Input and output of various file formats used by MD simulation codes, including LAMMPS, XYZ, CFG, IMD, DL_POLY, POSCAR, NetCDF, PDB, FHI-aims, CASTEP, XCrySDen, GALAMOST, Quantum Espresso and GSD/HOOMD.
Interactive visualization of a large numbers of particles and bonds using hardware-accelerated OpenGL rendering.
Support for various particle shapes: spheres, cubes, ellipsoids, cylinders and more.
An easy-to-use graphical interface and a data model that supports an arbitrary number of particle properties.
Non-destructive data manipulation and analysis functions are arranged in a data flow pipeline by the user. Parameters can be changed at any time and results will immediately be recalculated. Available modification functions include:
Manual selection of particles and inspection of particle properties
Useful analysis functions:
A modular software design, which allows extending OVITO via C++ plugins
