LAVA

Lava is a general-purpose calculator that provides a python interface to enable one-click calculation of the many common properties with LAMMPS and VASP. The name Lava is derived from the β€œLa” in LAMMPS and β€œva” in VASP. It provides a set of classes and functions to generate configurations, run lammps/vasp calculation, retrieve the output, postprocess and plot the results. All the above tasks are hard-coded into the script, without the need to call additional libraries.
