$useconstJg is a command to switch from sweeping voltage to sweeping of current density. Note that the program is still using bias as the boundary condition, therefore, the program will spend more time in finding the current density equal to the assigned value by adjusting the bias within the range.
$useconstJg type(=1) Jg -+
$useconstJg type(=2) Jg_min Jg_max Jg_step -
For example:
$useconstJg 1 10.0 -0.3 0.3 1.0e-5 1.0e-4
This mean the program will try to current current density = 10.0 (A/cm^2). The finding range is vgstart-0.3V to Vgstart+0.3V. It will goes to Vg in the range of 1.0e-5V. or the current density error is smaller than 1.0e-4
$useconstJg 2 10.0 200.0 20.0 -0.3 0.3 1.0e-5 1.0e-4
Note: Using $useconstJg, the command of Vgend and Vgstep will be disable. The program will only start from vgstart.
