Here post your question
Dear Gromacs team:
I am wondering if there are plans to reimplement support for user/table potentials. To my knowledge, support for this feature ended after Gromacs 5.0, and while it appears there were plans to reimplement this feature (User-Defined Potentials with Verlet Neighbor Searching), it seems to me it hasn’t been done yet.
We develop custom force fields that are neither LJ or Buckingham form, and in the past I’ve used table functions to do simulations in Gromacs with these force fields (e.g. https://pubs.acs.org/doi/full/10.1021/acs.jpcb.6b05328). But I haven’t been able to use Gromacs for this in several years do to the dropped user/table potential feature.
thanks very much,
Jesse
