Ovito 〈2026 Update〉

OVITO is an open-source, cross-platform software written in C++. It is specifically designed to handle large-scale datasets generated by atomistic simulations, such as those performed using popular MD codes like LAMMPS, GROMACS, or AMBER.

CNA can struggle at high temperatures where thermal vibrations blur the atomic lattice. PTM is the modern, more robust successor. It identifies structures even in noisy data and can output the local lattice orientation (quaternions), which is crucial for plotting orientation maps in polycrystalline materials.
