# Data and Scripts for "Accelerating Equilibration in First-Principles Molecular Dynamics with Orbital-Free Density Functional Theory" This dataset contains data and calculation scripts for the publication "Boosting first-principles molecular dynamics with orbital-free density functional theory". Its goal is to enable interested parties to reproduce the experiments we have carried out. ## Prerequesites The following software versions are needed for the python scripts: - `python`: 3.8.x - `mala`: 1.1.0 (with `dftpy` installed) Further, make sure you have a working `Quantum ESPRESSO` and `VASP` installation and have downloaded additional data such as local pseudopotentials and ML models (for references, see publication). ## Contents - `scripts/`: Example scripts for the three principal python tasks associated with out work: ML inference, trajectory analysis and OF-DFT-MD runs (via DFTPy). The scripts are general blueprints for these experiments and can be adjusted to perform all of the calculations given in the publication. - `data/`: Contains raw calculation data for the three investigated systems (hydrogen, beryllium and aluminium). Since the main goal of this work is to compare OF-DFT-MD initialized and ideal crystal structure initialized trajectories and inferences, each of the three system-folders contains a `MD_ideal_crystal_structure` and `MD_ofdft_init` folder, with ideal crystal structure and OF-DFT-MD initialized data, respectively. Therein, contents may differ; e.g. aluminium contains DFT calculation data, for beryllium data is divided by system size and Nosé mass, while for hydrogen data for different temperatures is given.
