$negfpoissonselfconsistent

$negfpoissonselfconsistent is the command to setup the max number of iterations and the region where we substitute the charge density generated by NEGF solver into Poisson equation.
Example:

$negfpoissonselfconsistent
100
27 57
# NitiSC
# chargereplacestart chargereplaceend

In this case, the max number of iterations is 100 and the region for charge replacement is from 27 to 57.
