Dear Amber Users

I am simulating the system of Ionic Liquids (ILs) with varying
concentration of ILs. In pure system (only ILs), I am getting total energy
 positive. As we add the water in the system the total energy becoming
negative. The value are mention below. I am using choline Lactate as Ionic
Liquids.

pure Choline Lactate +1807.48
0.5% Choline Lactate +1366.43
1.0% Choline Lactate + 905.64

Others system are negative.
It is possible that the total energy of the system is positive or I am
doing wrong simulation.

I validated the force field by comparing the experimental and simulation
density.

Please suggest me.

Thank you in advance
Rahman
