Hi all, I asked this before and I think I remember the answer, so this is just to make sure, before we move to another software package.
1. We need a sinusoidal force of given direction, amplitude, and frequency applied to a selected group of atoms. Mimicking it with giving those atoms charge and applying an electric field is not an option. Is there absolutely anything else we can attempt? 2. Is this something I could request as a feature that could be implemented quickly (within weeks)? Same type of mdp syntax, except also input for the group. If it takes a while, makes no sense for us to wait, because LAMMPS can do it. The issue with LAMMPS is that it is ~5 times slower than Gromacs when using similar forcefields.
