NELMGW

NELMGW = [integer]
Default: NELMGW = 1

Description: NELMGW sets the number of self-consistent GW steps, or the number of time steps used during time propagation. Available as of 6.3.0.

This tag is effective for ALGO=EVGW[0] | QPGW[0] | GW[0][R][K] | TIMEEV and ignored otherwise. For instance

ALGO = EVGW0
NELMGW = 4

performs a partially self-consistent GW calculations, where $G$ is updated four times.

Omit NBANDS and NELM to select the single-step GW procedure.

When ALGO = TIMEEV, VASP will perform a time-dependent calculation. NELMGW will determine how many time steps will be performed. If it is lower than 100 VASP will use the default value, 20000.
