[gmx-users] Nonsymmetric Potentials

I would like to use GROMACS for an assembly of elastic disks, and the
associated potential is therefore not symmetric:

V = 0   for   r > rcrit

V = k/2(r-rcrit)^2   for    r < rcrit

Can GROMACS be used for such potentials? I think that it may be possible to
use table-based interactions for this potential, and I am hoping that
someone can point me towards information on this topic.

Any help here would be greatly appreciated.
