Dear Professor Shirts
Thank you very much for the reply.
I thought about it more. It will also be good for us to use cutoff in the energy. This cutoff is for the maximal energy (for the nonbonded interactions).
Editing the RE function might be unnecessary (Another way of implementation).
In other words what is needed is to use cutoff for the energy so it won't be larger than a certain value (total VDW and electrostatic) and this value should be constant for all pairs.
Using cutoff in the bonding energy can also be used but it seems complicated and I'm not sure necessary.
Another small thing is if you know if you can exclude certain atoms from the non bonded interactions?
Could you help us with that?

I think you need to be more specific to get any useful response.

It's not clear what the purpose of adding a cutoff to the bonded term would

You need to specify what you are editing it to do!
