WARNING 1 [file topol.top, line 11462]:
The GROMOS force fields have been parametrized with a physically
incorrect multiple-time-stepping scheme for a twin-range cut-off. When
used with a single-range cut-off (or a correct Trotter
multiple-time-stepping scheme), physical properties, such as the density,
might differ from the intended values. Check if molecules in your system
are affected by such issues before proceeding. Further information may be
available at https://redmine.gromacs.org/issues/2884.

How to fix this problem

Hi!

The link in the warning is outdated (which version of GROMACS are you using), here is the working link: GROMACS can not reproduce properties with the GROMOS force fields - Redmine #2884 (#2884) · Issues · GROMACS / GROMACS · GitLab.

And here is the paper discussing the issues with GROMOS forcefield in more details: On The Importance of Accurate Algorithms for Reliable Molecular Dynamics Simulations | Theoretical and Computational Chemistry | ChemRxiv | Cambridge Open Engage
