Hi there.

2 plates with potentials, 5kV and other ground. In 0 folder, I set the electric potential accordingly.

For a different setup, I am trying to run this experimental case where "droplets enter this region when both electrodes are held at an identical high voltage between 2.8 and 3.4 kV creating a field-free region. The left electrode maintains a fixed HV while a stacked circuit of MTP1N100E MOSFETs switches the righthand plate from HV to ground and remains there for a variable time t ) 10-900 us before returning to high-voltage" (Grimm and Beauchamp, 2005)

How can I set this configuration? I want to avoid running the simulation from 0 to 10 us and then changing the setting and then continuing.
