These start switched off, which is the solver's default. Turn them on for realistic transistor currents.

a point lands here as each voltage is solved

profile what's going on inside the device at one voltage

runs

Every finished run stays on the curve as a faded line, labelled with whatever changed before the next run. Clearing the plot clears this list too.

device file

Saving keeps just the device: its shape, doping and mesh. The sweep and models aren't saved with it.
