Your first gpvdm simulation
•Save it somewhere but not in the install directory. 12
•Click on New simulation, in the file menu.

The core solver will be run on CPU 0
•Blue is CPU usage, red is disk usage, if you simulation is running slowly, writing to the HDD is always the bottleneck, SSDs highly recommended. 14

The snapshots window, this is used to show changes in the device as a function of voltage and time.
Set this to Ec.dat (The Conduction band/LUMO) 16

•Click play and the simulation will iterate through each voltage step. If you were doing a time domain simulation it would do the same.
