$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. You can also use this function and set the parameter with our GUI version at the input box of "Max Step","Repalced Charge Range" in GUI

$negfpoissonselfconsistent
self-consistent_iteration_steps
charge_replace_initial(cri) charge_replace_final(crf)
Note: The charge density in Poisson solver will be replaced by the charge density given by NEGF in the range from cri to crf.

Example:

$negfpoissonselfconsistent
100
31 40

In this case, the max number of iterations is 100 and the region for charge replacement is from 31 to 40.
