LANGEVIN GAMMA L
LANGEVIN_GAMMA_L = [Real]
Default: LANGEVIN_GAMMA_L = 0
When running NpT simulations with a Langevin thermostat (MDALGO=3), using the method of Parrinello and Rahman, the friction coefficient for lattice degrees-of-freedom have to be specified (in ps-1) by means of the LANGEVIN_GAMMA_L-tag. A fictitious mass for the lattice degrees-of-freedom has to be assigned using the PMASS-tag.
The friction coefficients γ for the atomic degrees-of-freedom are specified using the LANGEVIN_GAMMA-tag.
