Material structure processing software based on ASE (Atomic Simulation Environment) providing automation capabilities for calculating various properties of metals. Additionally, it aims to run and analyze molecular dynamics (MD) simulations using GPUMD.
- Based on the ASE package, MetalProperties-Automator supports different calculators such as calorine, DP, and LAMMPS.
- Allows for automated batch calculations of metal properties.
- Enables batch processing of files in the XYZ format.
- Integrated with GPUMD for performing molecular dynamics simulations, such as irradiation damage.
