NELMGW
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
ALGO = EVGW0 NELMGW = 4
performs a partially self-consistent GW calculations, where [math]\displaystyle{ G }[/math] is updated four times. All supported ALGO tags related to [math]\displaystyle{ GW }[/math] calculations are described here.
Omit NBANDS and NELM to select the single-step GW procedure.
