How to define LANGEVIN_GAMMA, LANGEVIN_GAMMA_L and PMASS par
Posted: Thu May 17, 2018 3:21 am
Dear Experts,
I am new to molecular dynamics simulations and I am interested in investigating behavior of crystalline solid material at a given pressure and temperature conditions. For which I have chosen NPT ensemble and which allows me to mimic given P-T conditions of the experiment. I am using VASP to perform MD simulations by enabling required flags for NPT ensemble using Langevin thermostat (https://cms.mpi.univie.ac.at/wiki/index ... thermostat). I have the following questions as a beginner.
1. Do we need to use only Langevin thermostat to perform NPT MD simulation as per the above link ? or Can I also use other Nose-Hoover or Nose thermostat ?
2. Can some one please explain me in detailed manner, how to define LANGEVIN_GAMMA, LANGEVIN_GAMMA_L and PMASS parameters of Langevin thermostat for simulating particular crystal system of interest or with any other example ?
Thanks in advance
Regards
