Important

Make sure that you use the MatPES-compatible pseudpotential versions (i.e. v.64)

matpes_static_job 

matpes_static_job(
    atoms: Atoms,
    *,
    level: Literal["PBE", "r2SCAN", "HSE06"],
    kspacing: float | None = 0.22,
    use_improvements: bool = False,
    write_extra_files: bool = False,
    auto_ispin: bool = False,
    prev_dir: SourceDirectory | None = None,
    **calc_kwargs
) -> VaspSchema

Function to run a MatPES-compatible static calculation.

Parameters:

  • atoms (Atoms) –

    Atoms object

  • level (Literal['PBE', 'r2SCAN', 'HSE06']) –

    The level of theory: "PBE", "r2SCAN", "HSE06"

  • kspacing (float | None, default: 0.22 ) –

    The KSPACING parameter to use. Default: 0.22 as in the MatPES paper. This is likely too expensive in many cases.

  • use_improvements (bool, default: False ) –

    Whether to make the following improvements to the VASP settings: ALGO = All, EFERMI = MIDGAP, GGA_COMPAT = False, ISEARCH = 1, and ENAUG deleted.

  • write_extra_files (bool, default: False ) –

    Whether to write out the following IO files: LELF = True and NEDOS = 3001.

  • auto_ispin (bool, default: False ) –

    If generating input set from a previous calculation, this controls whether to disable magnetisation (ISPIN = 1) if the absolute value of all magnetic moments are less than 0.02.

  • prev_dir (SourceDirectory | None, default: None ) –

    A previous directory for a prior step in the workflow.

  • **calc_kwargs –

    Custom kwargs for the Vasp calculator. Set a value to None to remove a pre-existing key entirely. For a list of available keys, refer to quacc.calculators.vasp.vasp.Vasp. All of the ASE Vasp calculator keyword arguments are supported.

Returns:
