GROMACS version: 2020.2
GROMACS modification: No
We often use user defined potentials in table files for simulations. Our cluster has recently updated the Gromacs version to 2020.2.
Previously, we have had to use the “group” neighbor cut-ff scheme as it would allow for User defined interaction potentials. However in Gromacs 2020.2, “group” is no longer supported.
Now, with the “Verlet” scheme as the only supported method - user defined potentials are not supported and grompp fails as I get the error “With Verlet lists only cut-off and PME LJ interactions are supported”. The manual also specifies that user is now not supported for electrostatics or vdw interactions.
Is there any way around this? OR are we constrained to use an older version of gromacs?
