NHC_NCHAINS
NHC_NCHAINS = [integer]
Default: NHC_NCHAINS = 0
Description: Length of the Nosé-Hoover chain.
NHC_NCHAINS sets the length of the chain for the Nosé-Hoover–chain (NHC) thermostat. Typically, this tag is set to a value between 1 and 5. The maximal allowed value is 20.
In case NHC_NCHAINS=0, the thermostat is switched off and the underlying dynamics generate a microcanonical (NVE) ensemble. NHC_NCHAINS=1 corresponds to the standard Nosé-Hoover thermostat.
