How do I specify tail corrections for the traPPE force field?

GROMACS version: 2020.3

My goal is to compute the self-diffusivity of methanol in the zeolite H-ZSM-5. I have started the first test simulations using the traPPE force field for methanol.

According to the traPPE web site (, simulations should be carried out with “analytic tail corrections for the Lennard-Jones Interactions”.
How do I specify such tail corrections in Gromacs?

The system is the same as I described in this recent post:
How will using “vdwtype = Cut-off” instead of “vdwtype = pme” affect the results?

More specifically:

LJ potentials are typically calculated using a site-site based spherical truncation at either 12 or 14 Å along with analytical tail corrections for the energy, pressure, and the chemical potential.

GROMACS supports such long-range corrections for energy and pressure (DispCorr = EnerPres) but has no ability to correct the chemical potential. Setting rvdw to 1.2 or 1.4 in concert with dispersion correction is the closest that GROMACS will get to being able to employ the force field as described.
