qimpy.dft.geometry.thermostat.Thermostat

class Thermostat(*, dynamics, checkpoint_in=(None, ''), nve=None, nose_hoover=None, berendsen=None, langevin=None)

Bases: TreeNode

Select between possible geometry actions.

Parameters:

• dynamics (Dynamics)

• checkpoint_in (CheckpointPath)

• nve (Union[dict, NVE, None])

• nose_hoover (Union[dict, NoseHoover, None])

• berendsen (Union[dict, Berendsen, None])

• langevin (Union[dict, Langevin, None])

__init__(*, dynamics, checkpoint_in=(None, ''), nve=None, nose_hoover=None, berendsen=None, langevin=None)

Specify one of the supported thermostat methods. Defaults to NVE if none specified.

Parameters:

• nve (dict | NVE | None) – [Input file] No thermostat (or barostat), i.e. NVE ensemble.

• nose_hoover (dict | NoseHoover | None) – [Input file] Nose-Hoover thermostat and/or barostat.

• berendsen (dict | Berendsen | None) – [Input file] Berendsen velocity-rescaling thermostat and/or barostat.

• langevin (dict | Langevin | None) – [Input file] Langevin stochastic thermostat and/or barostat.

• dynamics (Dynamics)

• checkpoint_in (CheckpointPath)

Return type:

None
