RANDOM SEED
RANDOM_SEED = [integer array]
Default: RANDOM_SEED = based on the system clock
Description: RANDOM_SEED specifies the seed of the random-number-generator (in case VASP was compiled with -Dtbdyn).
The random-number-generator (RNG) is used at several instances of a molecular dynamics simulation such as the initialization of atomic velocities, the Andersen thermostat (MDALGO=1 | 11), etc. The seed for the RNG can be supplied by the user by means of the RANDOM_SEED-tag. This is useful, for instance, if one needs to reproduce a previously performed calculation.
