Category:Thermostats

This category consists of thermostats used in molecular dynamics calculations for the NVT ensemble and NpT ensemble.

The user can choose between stochastic thermostats:

• Andersen thermostat.
• Langevin thermostat.

And deterministic:

• Nose-Hoover thermostat.
• Nose-Hoover chains thermostat

Mind:All three thermostats are available in the NVT ensemble but currently only the Langevin thermostat is available for the NpT ensemble.

The following table gives an overview of the possible combination of ensembles and thermostats in VASP:

	Thermostat
Ensemble	Andersen	Nose-Hoover	Langevin	NHC	CSVR	Multiple Andersen
Microcanonical (NVE)	MDALGO=1, ANDERSEN_PROB=0.0
Canonical (NVT)	MDALGO=1	MDALGO=2	MDALGO=3	MDALGO=4	MDALGO=5	MDALGO=13
	ISIF=2	ISIF=2	ISIF=2	ISIF=2	ISIF=2	ISIF=2
Isobaric-isothermal (NpT)	not available	not available	MDALGO=3	not available	not available	not available
			ISIF=3
Isoenthalpic-isobaric (NpH)	MDALGO=3, ISIF=3, LANGEVIN_GAMMA=LANGEVIN_GAMMA_L=0.0
