Ab initio Molecular Dynamics Trajectories for Hydrous Silicate Melts (NERC Grant NE/P002951/1)

Ab initio trajectories for the equilibrated MgO-SiO2-H2O melts at T = 1800 K and 3000 K are provided as "XDATCAR" files output directly from VASP for each simulation interval. Corresponding stress tensor components, required for calculation of viscosity via the autocorrelation function, together with the energy, temperature, and pressure are also provided for each iteration of the equilibrated trajectories. A full data inventory is provided in the READ_ME.txt file.

Statement
Ab initio MD calculations based on DFT were performed for a range of MgO-SiO2-H2O melt compositions under approximate transition-zone pressure-temperature conditions using the Vienna Ab initio Simulation Package (VASP) running on the ARCHER supercomputer. The electronic interactions were described by the projector-augmented wave (PAW) pseudopotentials using the Perdew-Burke-Ernzerhof (PBE) formulation of the generalised gradient approximation (GGA) exchange correlation functional with an energy cut-off of 550 eV sampling the Brillouin zone at the gamma-point. MD trajectories were calculated in the canonical (NVT) ensemble with periodic boundary conditions and a Nosé thermostat.
