Hi All
        I was running MD simulation in NVE ensemble and after running for
about 1 ns, i found that C:CA bond is getting stretched and after about 3
ns, this bond is almost 3.68 A long. What may be the reason for this
problem and how can i solve this problem? during equilibration phase i
heated my system from 0 to 300 K by constraining backbone atoms not to move
and every other atom was allowed to move.

Thank you for your help.
