Thanks Justin for your quick reply. What are the correct non-bonding settings for CHARMM to be used in the .mdp file?
Here is how the CNT molecule looks like prior to energy minimization. pre energy min CNT <https://drive.google.com/file/d/0B7SBnQ5YXQSLX0dIOHZjT3p1Y2s/view?usp=sharing> I am not continuing any of the equilibration steps anymore. As you can see the CNT structure is distorted badly. Please help me out. What settings do I need to change in order to avoid such distortion? Is there a possibility that the cnt topology was wrong to begin with?
