Description: The number of subdivisions of each RESPA step used in the integration step used in propagation of thermostat variables in the Nosé-Hoover–chain (NHC) thermostat.


The RESPA steps used in in propagation of thermostat variables in the Nosé-Hoover chain thermostat are treated by Suzuki-Yoshida scheme[1][2], whereby each step is subdivided further into NHC_NS parts. First, fourth, and sixth order schemes with, 1, 3, and 7 steps, respectively, are supported.
