Sorry for the very late response. I was able to create some grids and run some simulations. Thank you for the help!

Hi Nagendra, GridForces has the ability among others to apply a voltage that depends on the position in space.
You'll need to create an OpenDX file for your potential for your decaying voltage. One way that I used for this was a Python script that uses the gridData module packaged with MDAnalysis. There are certainly other solutions--_000_CH2PR11MB42933BE045446DB1151FA97FA70E9CH2PR11MB4293namp_--
