NELMGW = [integer]
Default: NELMGW = 1

Description: NELMGW sets the number of self-consistent GW steps. Available as of 6.3.0.

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

ALGO = EVGW0
NELMGW = 4

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