[gmx-users] charge vibrating periodically

[abhijit Kayal]

Dear GROMACS users,
            Recently I came across a paper where they have mentioned that
they placed a vibrating charge near CNT surface. The vibrating charge
satisfies the following relation z(t) = Acos(2*pi*f*t+phi), where A is
amplitude, f is vibrational frequency and phi is initial phase. So my
question is how can I incorporate the vibrating charge in gromacs. In this
paper they performed the simulations in gromacs. Any kind of help is highly
appreciated.
 Here is the link of the paper:

Thanks
 Abhijit
