Hi Justin,
the snapshot I uploaded in the URL is of the SSDNA-CNT
system after energy minimization step not before it. I stripped off
water and ions from the system for the ease of visualization. I would
be grateful if you suggest me a possible way out.
I don't see how that changes what I've said. You have a topology problem with
the CNT. Simplify the system - build a smaller CNT, minimize it in vacuo, etc,
then make it bigger/more complex. Look at the atoms that are distorting and
check the existence of their bonded interactions and associated parameters.
