LANGEVIN_GAMMA = [Real array]
Default: LANGEVIN_GAMMA = NTYP×0.0 

Description: LANGEVIN_GAMMA specifies the friction coefficients for the Langevin thermostat (in case VASP was compiled with -Dtbdyn).


The friction coefficients γ for the atomic degrees-of-freedom of the Langevin thermostat[1] (MDALGO=3), are specified 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.
