molecular dynamics for liquids

[shyama]

Sir

I am trying to simulate a system of ionic liquids using reaxx force field available here with prerequisites from publications regarding temperature and time steps.But I find in the output files that the molecules dissociate.How do I rectify this?

Please be more specific on what are your actual problem and question, and what system, force-field and publications you are talking about.
