Dear AMBER
I am trying to study the electrostatic and VDW interactions between two fragments. At the same time, I would like to freeze each fragment, i.e. minimize only the distance between the two fragments based on the non-bonded interactions. I applied a harmonic force on each fragment of 0.2 kcal/mol and minimized the system. Is that a right way?, also I was wondering how should I account the effect of the applied harmonic force. How can I ensure the harmonic force has no effect on the net non-bonded interactions between the two fragments.
Any kind of help would be highly appreciated.
Thanks in advance
Eliac
