Thank you Vedat!

Why do you use -DFLEXIBLE in md and in em?
Why dont you use constraint algorithm (LINCS) in your simulation?
Otherwise, the system is easily explode with lots of LINCS warning.


That could well be the phenomenon referred to at the end of http://www.gromacs.org/Documentation/Terminology/Blowing_Up. If you equilibrate with a small time step, you should be able to simulate with constraints, which is more efficient and probably a better model of real physics.
