There are two variants of non-polarizable force field model, (1) OPLS-AA without charge rescaling, (2) OPLS-AA with charge rescaling. For the second one the ions' charges are rescaled by 0.8, and rest of the force field parameters are same as the first one. Initial configuration of the electrolyte solution is generated using PACKMOL package. The MD simulation is performed using GROMACS 2019.3 51 package and the MD timestep is 2 fs.
