Hey Zach, You may be best off starting from the free energy code. It can be used to perturb charges and other things during a simulation. Hope it helps, Tsjerk On Sep 13, 2011 2:55 AM, "Zach Levine" wrote: Hi everyone, I'm trying to implement time-varying charges for various ions located in

Hi everyone, I'm trying to implement time-varying charges for various ions located in ions.itp in GROMACS 4.5.4, but I'm not sure where to begin. I've already had some luck implementing AC external electric fields by modifying /src/mdlib/sim_util.c, but this required minimal work from me and a fe
