Canonical sampling through velocity rescaling
WebThe simulation is 200 steps long with a 10 a.u. time step, using the stochastic velocity rescaling thermostat with a relaxation parameter of 100 a.u. and a target temperature of 200 K. Center-of-mass rotations and translations will be removed every 10 steps and trajectory information will be output to the xyz file every 5 steps.
