NELMGW = [integer]
Default: NELMGW = 1
Description: Controls 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
NELMGW = 4 and ALGO = EVGW0
performs a partially self-consistent GW calculations, where G is updated four times.
