about FGSF method in lammps

Is there any alternative method to Fennell and Gezelter shifted force (FGSF) method to simulate ionic liquids system, which is talking more time, can u suggest me to do my job faster

Thank you

I don't know what FGSF is or how it maps to something
in LAMMPS. You'd be better off to find different ways
to do ionic liquids in the literature, then ask if LAMMPS
can do something specific that you find.
