Justin, thank you.
In fact I am worried about the cross coupling terms which apper i the
functional form of COMPASS and CVFF.
As far as I know in GROMACS there are no such terms, so I am asking if
there might be a solution to include these by editing .itp, nb.itp,
bon.itp, .rtp, etc, without the need to modify the gromacs CODE.
These are very complicated functional forms, indeed. You may be able to use
tabulated bonded potentials, but I don't have much experience in that arena, so
I don't know if even that would be possible.

Dear all,
does anyone know if it is possible to somehow use COMPASS or CVFF
forcefields in Gromacs?
You can probably implement just about anything by creating the right files
(.itp, nb.itp, bon.itp, .rtp, etc). Quite a bit of work, but not too
conceptually difficult. Whether or not there need to be changes to the
source code to accommodate new force fields may be another issue.

Thanks,
