LANGEVIN GAMMA
LANGEVIN_GAMMA = [Real array]
Default: LANGEVIN_GAMMA = NTYP×0
Description: LANGEVIN_GAMMA specifies the friction coefficients (in ps-1) for atomic degrees-of-freedom when using a Langevin thermostat (in case VASP was compiled with -Dtbdyn).
When using a Langevin thermostat[1] (MDALGO=3), the friction coefficients γ for the atomic degrees-of-freedom are specified (in ps-1) using the LANGEVIN_GAMMA-tag.
One has to specify a separate friction coefficient for each of the NTYP atomic species found on the POTCAR-file.
